For anyone taking the ACT in 2015, it is important to be aware of a couple of major changes to the test format that have taken place.
1. The ACT Reading is consistently having one “comparative” reading section, in which there are two smaller passages (Passage 1 and Passage 2) instead of one larger one. The two passages are about a similar topic, yet have different perspectives. Students typically have to answer 7 questions about the individual passages, and then answer 3 questions comparing the two passages. Fortunately, the ACT has placed all the comparative questions at the end of the series of questions (e.g. questions 21-27 about the individual passages and questions 28-30 are comparative.)
The Reading passage with the comparative passages has consistently been the Humanities section. The only publicly released example of an ACT comparative passage can be found here:
I have an example of a comparative passage in my ACT Book with Barron’s Educational Series.
2. The ACT Science Section has had 6 passages instead of 7 passages on both the February and the April ACT in 2015. If you would like to see a sample of what this looks like, you should order the Test Information Release for the April ACT, as there are currently no publicly available examples of this different format. This shouldn’t affect your approach to the science too much, other than as far as pacing, you should spend about 6 minutes a passage instead of 5.
