Yale will again require standardized test scores

Yale just announced that they will again require test scores as part of the college application. In addition to SAT or ACT scores, students can now submit Advanced Placement or International Baccalaureate results. Yale made this shift because it will improve their ability to predict which students are most likely to succeed at Yale:

“Yale’s research from before and after the pandemic has consistently demonstrated that, among all application components, test scores are the single greatest predictor of a student’s future Yale grades. This is true even after controlling for family income and other demographic variables, and it is true for subject-based exams such as AP and IB, in addition to the ACT and SAT.”

In addition, Yale found that including standardized test scores would serve to increase the diversity of its class:

“Our researchers and readers found that when admissions officers reviewed applications with no scores, they placed greater weight on other parts of the application. But this shift frequently worked to the disadvantage of applicants from lower socio-economic backgrounds.” Source: https://admissions.yale.edu/test-flexible

Students looking to apply to highly selective schools would be well-served by showing their readiness for college level work by doing their best on the SAT or ACT.

Is the Digital SAT easier than the old paper SAT?

Many students and parents who were familiar with the old paper-based SAT are wondering whether the new Digital SAT will be easier.  The Digital SAT is designed to maintain the same level of rigor and predictive value for colleges as the paper SAT—otherwise, it wouldn’t be a useful tool to assess freshman-year readiness.  The College Board has done extensive research to ensure that Digital SAT scores align with paper SAT scores.  That being said, students I have tutored have generally found the new Digital SAT to be much less intimidating and more approachable than the paper SAT.  Here are ten reasons why most students will find the Digital SAT easier than the paper SAT. 

1.  Test fatigue is much less of an issue.  While the paper SAT was over three hours long, the Digital SAT is only a little over two hours.  This is possible because of the section-adaptive format of the Digital SAT:  students start with modules of average difficulty and then progress to either more or less challenging modules based on their first module performance.  Most students find that sustaining their attention for a little over two hours is quite manageable, making the Digital SAT less overwhelming than the paper SAT. 

2.  Less time wasted on double-checking.  On the paper SAT, many students found it difficult to avoid looking back at their previous answers since they could easily be seen.  Also, they had concerns about their bubbling in of the paper answer sheets. On the Digital SAT, students will only view one question at a time, making it much easier to compartmentalize their focus on one task.  Also, students click on the answer instead of physically bubbling, and they can easily see that the answer choice they selected is recorded by the computer. 

3.  Calculators are available throughout the math section.  The paper SAT had a no-calculator section; even though all the problems on this section could have been done without a calculator, many students found it more challenging than the calculator math section.  On the Digital SAT, students can bring a calculator of their own to use for the math sections.  Moreover, they have access to the powerful Desmos™ calculator that is built into the testing interface.  The functionality of the Desmos™ calculator allows students to easily graph parabolas, systems of equations, and even tables. 

4.  Fewer questions on obscure grammar concepts.  The Digital SAT focuses on grammar fundamentals:  subject-verb agreement, verb tense, punctuation, modifier placement, and transitions.  Unlike the old SAT, which also tested idioms, diction, and wordiness, students will find that they can focus their grammar study on certain concepts.  For example, understanding the rules of semicolon and colon usage can go a long way on the Digital SAT. 

5. The question stems are more predictable.  Unlike the paper SAT, which had a wide variety of question wording, the questions on the Digital SAT are quite consistent.  Students will find certain question stems repeated over and over: 

Which choice completes the text with the most logical and precise word or phrase?  

Which choice best states the main purpose of the text?

Which choice most logically completes the text? 

Which choice completes the text so that it conforms to the conventions of Standard English?  Which choice completes the text with the most logical transition?  

Having these consistent question stems allows students to get in a better testing rhythm and devote more time to thinking about their answers instead of trying to understand what they are asked to do. 

6.  The reading and writing selections are concise.  The old paper SAT had just a few reading and writing passages, each of which was several hundred words.  If a student found a topic uninteresting on these sorts of passages, it was easy for them to lose focus.  On the Digital SAT, the reading and writing passages are no longer than 150 words and are accompanied by a single question.  While a shorter text doesn’t necessarily mean an easier text, it does mean that students will often find them less daunting than the longer old SAT passages. 

7.  Proctor errors are less of a concern.  I have had some past tutoring students experience proctor errors during their testing—in particular, the proctor called “time” too early or too late.  Since the timing on the Digital SAT is done within the testing application, students need not worry about time being called early.  If they hide the countdown clock, it will automatically reappear when 5 minutes remain.  That way, students can be sure they answer every question before they run out of time. 

8. Students can use their own tablet or computer.  Familiarity brings comfort—students can practice on the same tablet or computer they want to use on test day.  Students can take control of their testing process by ensuring their computer is fully charged and in good working order.  There should be a minimal disconnect between practice tests and real tests when the device is the same for each. 

9.  The questions are less wordy.  Both the reading/writing and the math questions on the Digital SAT are generally shorter than those found on the paper SAT.  If students take their time carefully reading the questions, they are unlikely to make careless reading errors. 

10.  The Digital SAT is almost exactly like the Digital PSAT.  While there are slight differences in the content tested on the SAT and PSAT, the two tests have the same format and time restrictions.  Students who took the PSAT in the fall will feel comfortable knowing that they have already seen the computer interface and question types they will see on the Digital SAT. 

All told, students should look at the new Digital SAT not as something to be feared, but as an outstanding opportunity to demonstrate their academic skills to colleges.

Solutions

1. B.  The information before the blank is saying that the author doesn’t exactly know why Dorrington never cashed the 10,000-pound check. The sentence with the blank is saying that the check was found in his possession. The author is not repeating previous information, so answer A is incorrect. Answer C makes no logical sense. Answer D is incorrect because the author is not contrasting the two sentences. Instead, the author is offering more information about the check, making option B the best answer.

2. A. The general meaning of this passage is that George Tackle had no reason to be notable, except that his father was notable. This makes option A the best answer since we are contrasting the lack of importance of the son with the “pull” he gets from his father. Option B is incorrect as it makes the second sentence a fragment. Options C and D are incorrect as the author is not showing cause and effect. 

3. B. Here, the author is setting up a contrast. We learn that Tim is making snoring noises, but he is still watching through the mosquito netting for a shadow. Therefore, he isn’t actually asleep. The only answer option that shows the contrast between the snoring noises and his being awake is option B.

4. C. Notice the word “and” before the blank. This eliminates option A. Option B is incorrect as we are not placing things in order. Option D is incorrect as the author is not concluding. The author is offering additional information, making option C the best answer.

5. D. In this passage, the second sentence is showing an example of an attribute The Wiggle had which other small steamers did not have. This makes option D the only appropriate answer.

6. D. The author is offering more information here. The woman has refused thanks and set them on the shore. This makes option D the best answer. The author is not showing cause and effect, making A and B incorrect and is not showing contrast, making option C incorrect.

7. B. The sentence shows that the portions are full of motion. The author wants to contrast this with the motion never being regular or in one place. This contrast is best shown in answer B. Answer A leaves the sentence a fragment. Options C and D do not show contrast.

8. A. The context clue here is that they found “pleasant fellows” but Bertram was “in low spirits” these are two contrasting emotions, making “however” the best answer. Option B would need to be placed with the first item of contrast, not the second. Option C shows cause and effect, not contrast. Option D does not fit into the context of the sentence.

9. C. In this sentence, the author is adding more information to emphasize the information in the first sentence that “this was the last I saw or heard of [them] for many a long day”. This makes option C the best answer as it shows that what is coming next is additional information. Option A does not fit into the sentence structure of the second sentence. Option B shows cause and effect. Option D shows contrast.

10. D. The first sentence sets up that he could not do what he did. The second sentence explains why he could do that after all (by breaking rules). The keeping of the rules is to be assumed, thus “of course” is the best answer. The breaking of rules is not to be assumed. Options A, B, and C do not fit into the structure of the sentence.

D. After its nearly complete destruction in a fire in 363, the Temple of Apollo Palatinus was not restored, leaving only fragments.

2. While researching a topic a student has taken the following notes:

  • The Fountain and Tallman Museum is located in the historic Fountain-Tallman Soda Works building in Placerville California.
  • The building is unique in its construction as it has stone walls that are over two feet thick—originally designed to keep ice and other soda making equipment cool. The thick walls are why it still stands when most other buildings from that era have not survived.
  • In addition to being a soda water factory, the building was also used as a jail and an office space for a gas company.
  • In the late 1900s the building was donated to a local historical society and was set up as a museum of local history.

The student wants to introduce the historic Fountain-Tallman Soda Works building to an audience that has never heard of it before. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. The Fountain- Tallman Soda Works building is a historic building in Placerville California that was built as a soda water factory but has served the community in several capacities since its construction.
B. The Fountain-Tallman Soda Works building is currently a museum with walls that are over two feet thick.
C. The Fountain and Tallman Museum started with the donation of a building to a local historical society in the late 1900s.

3. While researching a topic a student has taken the following notes:

  • Balsamic Vinegar of Modena (BVM) and Traditional Balsamic Vinegar (TBV) are two different products with different standards.
  • BVM has lower standards, and is much less expensive, is often aged only briefly, and contains  some ingredients that are not traditional.  It is protected under the weak European protected geographical indication (PGI).
  • TBV is aged at least 12 years, but often much longer, and has stricter controls on ingredients as well as origin as it is regulated under the strong European protected designation of origin (PDO).
  • Neither PGI nor PDO are able to be enforced in the U.S. so if consumers want to purchase real balsamic vinegar, they must be careful to read the name and look for the PDO or PGI seal on the label.

The student wants to explain to readers in the United States the variety of goods they might see labeled as “balsamic vinegar” in the grocery store. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. Both BVM and TBV can be found in the United States, but only if a discerning shopper knows where to look.
B. Because PGI and PDO are not enforced in the United States, a wide range of products, from artificially dyed vinegar to authentic TBV and BVM, may be labeled as balsamic vinegar in American stores.
C. Authentic BVM and TBV both have strict quality controls at their points of origin in northern Italy. Shoppers can be confident of authenticity by looking for PDO and PGI seals.
D. BVM and TBV are both protected in some way, with BVM having lower standards and TBV having higher standards.

4. While researching a topic a student has taken the following notes:

  • As a type of antibody, Immunoglobulin G (IgG), binds with many pathogens in the body in order to protect the body from infections brought on by viruses, bacteria, and fungi, among others.
  • IgG is the most common antibody in blood circulation and makes up around 75% of serum antibodies in humans.
  • If doctors suspect certain conditions, they may measure a patient’s levels of IgG as a diagnostic tool.
  • IgG plays a key role in newborn immunity as infants inherit IgG from their mothers through both placenta while in utero and through breast milk once born.

The student wants to include in her essay a sentence that will highlight the importance of IgG to all humans. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. IgG makes up around 75% of the average human’s serum antibodies and plays a key role in protecting the body from a wide range of infections.
B. Infants receive IgG in multiple ways from their mothers, including through the placenta and through breast milk.
C. IgG levels are used by doctors occasionally as a diagnostic indicator for certain specific conditions.  
D. While important, IgG is not the only antibody that helps support immune reaction in humans who have been infected by a virus, bacteria, or fungi.

5. While researching a topic a student has taken the following notes:

  • Mary Quant was one of the designers who helped to define 1960’s style in the United States and Great Britain.
  • Quant specialized in youthful looks with bold colors, blocky shapes, and wild patterns, though her earlier work was a bit softer and more delicate than her later work.
  • While Quant claimed to have invented the mini-skirt, some people dispute this claim, saying that the mini-skirt was invented by one of several other designers or that it was not invented by any one person, but was rather the logical end point of a continuous trend of shorter hem lengths.
  • In addition to clothing, Quant designed headwear, household goods, and personal care items, like makeup.

The student would like to explain to designers already familiar with Quant the range of her designs. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. Quant designed not just clothes we now consider classic, like the mini skirt, but also tried her hand at designing household goods, hats, and makeup.
B. Quant had a distinctive style that changed slightly over the course of her career, moving from slightly more soft and delicate to wild patterns and colors.
C. Mary Quant helped shaped style in the 1960s with her design for the now famous miniskirt.
D. With the consistently shortening hemline as a general trend, Mary Quant showed her design skill by creating the mini-skirt, a now famous look.

6. While researching a topic a student has taken the following notes:

  • While China’s imperial era is often associated with Emperors, Empress Dowager Cixi who lived from 1835 until 1908 had effective rule over the country from 1861 until her death.
  • Cixi came to power when emperor Zianfeng died, leaving Cixi’s son to inherit the throne at age five.
  • Cixi schemed to overthrow other appointed regents and served as co-regent alongside another advisor Empress Dowager Ci’an for her son’s entire life, since he was seen as a weak ruler.
  • Upon her son’s death Cixi conspired to have her young nephew placed on the throne so that she could continue in her role as regent.

The student would like to explain how Cixi managed to remain regent for so long. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. Empress Dowager Cixi reigned as regent for more than 70 years, an impressive feat for any ruler, but most especially for a female ruler of the 19th century.
B. As one of the backbones of China’s imperial era, Empress Dowager Cixi is likely remembered as the longest reigning female monarch, though she was only technically the regent.
C. In order to ensure her power, Cixi overthrew other regents so that she could control the monarchy through her son.
D. Cixi reigned for over 70 years by first serving for regent for her son and then, after his death, scheming to have her nephew put on the throne so that she could continue as regent.

7. While researching a topic a student has taken the following notes:

  • The first woman to ever be granted membership in the Entomological Society, Cynthia Evelyn Longfield was a renowned entomologist who specialized in the study of dragonflies.
  • Born in 1896, Longfield served in the Army Service Corps in World War One. After the war she traveled extensively, collecting specimens for the Natural History Museum of London.
  • In World War Two she served in the Auxiliary Fire Service.
  • Later in life she was a cataloguer at the Natural History Museum and collected 38 species of butterflies on a trip to South America. Three of those species had never been seen before.

The student wants to emphasize Longfield’s dedication to public service. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. Longfield is best remembered for her trip to South America, on which she catalogued 3 species of dragonflies which had never been seen before.
B. As the first woman to be granted membership in the Entomological Society, Longfield is well remembered in certain circles for her pioneering work with dragonflies.
C. While she is remembered for her entomological work, Longfield served her country in both World Wars I and II first in the Army Service Corps and Later in the Auxiliary Fire Service.
D. Longfield once, in her job for the Natural History Museum, collected 38 species in one single trip to South America.


8. While researching a topic a student has taken the following notes:

  • Kepler-90 is a star around 2,000 light years away from earth in the Draco constellation. It’s planetary system is quite similar to ours, as was discovered by the Kepler mission in the early 21st century.
  • The Kepler mission was designed to discover planets that orbit their stars by measuring dips in brightness of the stars as the plants cross them.
  • Kepler-90 has 8 planets just like our solar system’s sun does, however, it is thought that several of the planets that orbit Kepler-90 do not rotate on their axes, leaving them half in the dark, much like Earth’s moon.
  • Kepler-90 cannot be seen with the naked eye from Earth.

The student wants to explain the purpose of the Kepler mission and what it discovered at Kepler-90. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. The Kepler mission measured the light coming from stars including Kepler-90—a star about 2,000 light years away from earth.
B. Designed to discover planets orbiting stars, one of the Kepler mission’s findings was the eight planets orbiting Kepler-90, some of them not turning on their axes.
C. Since Kepler-90 cannot be seen with the naked eye, it took a special mission, the Kepler mission, to discover its 8 orbiting planets.
D. The Kepler mission confirmed the presence of many planets by measuring dips in light coming from far distant stars.

9. While researching a topic a student has taken the following notes:

  • Yang Xiong was a Chinese author and philosopher of the early 1st century CE. He was well-known in his time in the Han dynasty.
  • Yang gained enough praise and acclaim, that he was summoned to imperial capital where he was an officer in charge or composing fu as well as poetry for the emperor.
  • Yang did not think that the nature of humanity was inherently bad or good, but rather, he philosophized that human nature was a mixture of both.
  • His most famous work, Exemplary Sayings, is remembered for his critique of his contemporaries for their overly elaborate writings and their seeming inability to address the greater moral issues of the day.  

A student wants to give an overview of the beliefs of Yang Xiong. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. As a Chinese philosopher of the early 1st century CE, Yang Xiong wrote for the emperor on a regular basis. His work was both poetry and fu as the situation demanded.
B. Exemplary Sayings is Yang Xiongs most well remembered work because  it contained criticisms of other writers.

10. While researching a topic a student has taken the following notes:

  • In many building trades like woodworking, masonry, and metalworking, workers use what is known as a combination square for a multitude of situations.
  • The combination square is made up of a ruler, and one of may different heads that can be slid over or along the ruler. A worker might use a standard head, a protractor head, or a center finding head.
  • The modern combination square dates back to the 1970s and can be used with its standard head to make 90 degree markings, miter corners, check whether a surface is level, gauge depth, and other activities vital in building.
  • With other heads, the abilities of the combination square are much more complex.

A student wants to explain to a friend a situation in which a combination square with a standard head might be useful. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A. The combination square can be used for a great many things, especially if the person using it has more than one head for the tool.
B. With a standard head, a combination square could be used in building to make sure walls are level and corners meet at exact right angles.
C. Woodworkers, masons, and metalworkers all use the combination head in their daily jobs.
D. Depending on the situation, a builder may switch out the heads of a combination square to complete different tasks.

Solutions

1. D. The question requires that the answer explain why the entire temple can’t be seen today. While the notes given do include information on an early fire, it also explains that the temple was restored after that first fire in 64 CE. That would point us to the second fire in 363 CE as the final destruction of the temple and the reason why it is not visible today, making answer option D the correct answer. Answer option A explains why parts are visible today, but not why the rest of the temple is not visible. Answer option B explains the earlier destruction prior to the restoration. Answer option C includes information that does not answer the question.

2. A. The question asks for a general introduction to the building for an audience that is completely unfamiliar with the building. This makes answer A the best option as it gives the best broad background for the building. Option B gives just one detail of the building, not an introduction. Option C gives an introduction to the museum, not the building. Option D gives the origin of the building, but no information as to the rest of its history or relevance today.

3. B. The question asks about the variety found on the stores in the U.S. The final note of the set indicates that, due to lack of protections, in addition to real BVM or TBV there are many knock off products in the U.S. This makes option B the best to answer the question. Option A does not explain the variety available beyond BVM and TBV. Option C explains how to find BVM and TBV, but not what else is on shelves. Option D explains the protections on BVM and TBV but not the variety of other goods available.

4. A. The question asks about the importance of IgG to all humans. Option A best explains that IgG plays a key role in protecting all humans from illnesses. Option B explains how infants get IgG, but not its role. Option C explains how it can be a useful diagnostic, but only for people with certain conditions, not for all humans. Option D implies that IgG is plays only a part in immunity and therefore does not highlight its importance to all humans.

5. A. The question asks for an answer that assumes the reader already knows something about Mary Quant and that explains her range beyond just fashion design. Answer A fulfills this prompt by explaining that she designed household goods, hats, and makeup. Option B is incorrect as it explains a slight and gradual change over time, not a wide range of designs. Option C is incorrect as it gives a general introduction to Quant, but does not explain the range of her designs. Option D is incorrect as it addresses just one of her designs instead of showing her range.

6. D. The question asks for an explanation of how Cixi managed to rule for so long as regent. Option D explains this the best by telling the reader that Cixi ruled not just during her son’s childhood, but also by placing another child on the throne after her son’s death. Options A and B are incorrect as they do not explain how she ruled for 70 years. Option C is incorrect as it explains how Cixi came to power, but not how she retained that power for 70 years.

7. C. The question asks for information on Longfield’s public service, not her entomological activities. This makes C the best option and A, B, and D incorrect.

8. B. The question asks for the purpose of the Kepler mission and what was discovered at Kepler-90. Option B is the best answer as it explains that Kepler was designed to discover planets orbiting stars (its purpose) and what it found at Kepler-90 (8 orbiting plants, some of which do not turn on their axes). Option A explains what Kepler did, but not what it discovered at Kepler-90. Option C explains why the Kepler mission was necessary, but not what its purpose was. Option D does not explain specifically what was discovered at Kepler-90.

9. C. The question asks about Yang Xiong’s beliefs. This is best summed up in option C. Option A explains his work. Option B explains why his work Exemplary Sayings is remembered. Option D explains his attitude toward his contemporaries.

10. B. The question asks for a situation in which a combination square with a standard head would be used. We learn in the notes that with a standard head, the combination square can be used to mark 90 degree (right) angles, miter corners, check for level surfaces, and gauge depth. This makes answer B the best option and the other answer incorrect.
