Editor's Notes

May 13, 2020:

Just like with our selection of SAT prep books, we prioritized choices that are comprehensive, written by authorities in the field, full of study strategies, and designed to help you not only become comfortable with the material as it is presented on the exam specifically, but also capable of helping you boost your score.

The ACT's content has not seen any notable changes since 2014, but we still overhauled this list to ensure every edition was up to date. None of the books here were printed prior to those amendments, so you can feel confident regardless of your choice.

Today we removed 36 in Just 7 Steps, which is a nice addition to have for some, but not strong enough to keep when volumes like For the Love of ACT Science are around, which we added in its place. This one was developed by a chemical engineer who knows his stuff, and it's written with an extremely approachable tone, clearly explained, and engaging enough that even students who loathe science will likely enjoy it at least a little bit. It's been revised since its initial 2015 release so that it contains new and updated tactics and fresh presentation of certain concepts.

And while you can access past tests in PDF form online, we still kept The Official ACT Prep Guide on our list, as having something in print is quite different than seeing it on a tablet or laptop. It has been recently updated and comes with bonus online content, which adds to its value, and works extremely well in conjunction with the ACT Prep Black Book.

For more practice tests, consider 8 Practice Tests for the ACT by Kaplan, although be aware that many students find these to be easier than the actual exam. It's a great place to start, however, and useful for finding out where you already shine so you can focus on trouble areas.
