Improved my score

"Previously, I was 1 point short on my first attempt at the ACT. I prepared with another book. I decided to take a few practice tests in this book a week before testing, and I improved my score by 3 points (2 more points then what I needed). Highly recommend!"

The ONLY Prep book students should use

Reviewed in the United States on June 21, 2021 Verified Purchase

"I have been an ACT tutor for over 10 years. This is the only book students should use to prepare. Other publications don't pay attention to detail, such as running tests over onto 2 pages, back and front, making it more difficult. They also don't always have content taken from actual ACT tests, so the study material does not match the actual test."

Really helpful

Reviewed in the United States on February 6, 2022 Verified Purchase

"My son is homeschooled so he doesn't have a lot of experience taking timed tests. This book was helpful in getting him used to the process and understanding how to work with timed tests and find the strategy that worked for him. The book also had some great tips in it as well. Would definitely recommend as a tool to help with ACT prep."
