Save yourself a lot of wasted time and simply avoid this book... I bought it at a half-priced book store for some extra practice. The math is more simplistic than that of the actual ACT, although anyone who has taken Trig in high school should do fine on math. I bought this primarily for the English review tests. I took several and found myself missing around 10-15 on each test. Now don't get the wrong idea, I'm not dumb. This book is awful. I had a teacher who used to do ACT prep look over my tests, and he openly admitted that the book was wrong. I then got an official ACT practice test from my guidance office, and it was a completely different story. I didn't miss any on the English section. Math was slightly more challenging (it took me more than 25 minutes to finish it). The reading and science are extremely easy sections, but still take practice tests for them, so you can learn how to pace yourself. If you have unlimited time, you could easily get a 36... Please, please, please do not make the same mistake I did and waste valuable time with this book. Get the official ACT Prep book, so you can get a real feel for the test. You will do fine once you get a handle on the structure. The biggest thing is confidence, and this book gives you both a false sense of confidence, and in some cases a false sense of insecurity. I got a 36, so if you are distraught over a poor performance on these tests, you shouldn't be. Go for the real thing, save yourself from the stress.

Please do not waste your time with this book. I am a senior who is going through some stressful times with appying to colleges, however my ACT score isn't really up to par. I bought this book wanting more practice. After purchasing it and doing as many as five whole ACT practices tests from it, I developed a sense of confidence. I thought the real ACT would be a cinch, however it's nothing like the level of difficulty as the ones in this book. Please do not buy it. I've wasted enough time with it. It has gotten too many errors with the answer key, questions, etc. Buy Kapaln's or other books from the other companies. STAY AWAY FROM THIS ONE!!! PLEASE!!!

I'm a student, as of right now going into my senior year of high school. I've taken the ACT a few times and received a good score, but the scholarship I want for the school that I'm going to requires a score a single point higher than my current best.

To practice and make sure I got the ACT score I needed, I acquired 3 different books, and this was one of them. And I'd have to say, this is definitely the least helpful of those three.

Don't let the claim "as close as you can get to the real thing" fool you. As someone who has seen multiple real ACT tests, I can tell you the feel is completely different, especially the English sections.

Furthermore, there are multiple glaring errors, including grammatical errors in the questions and passages ("J. Dark matter has not effect at all...") as well as in the answer keys. In the first test, an explanation for a question told that using "it's" was incorrect for a possessive pronoun, right underneath bold letters declaring the correct letter choice was the one corresponding to what it had just explained as wrong.

And last, but not least, this book lacks entirely a subscoring key. The real ACT, as well as practice tests in better books, divide questions based on the skills they measure and give a score out of 18 (except the science test). Being able to get your subscores give you a more accurate picture of how well you do and where you need to improve. This book, however, simply tells you to divide your raw score by the number of questions, multiply by 36 and add or subtract a correction factor. This is not helpful in the least.

As advertised, this book does in fact have 10 tests that can be used for practice, but if you've already taken the test and you're really serious about improving your score, this is not the way to go.

I bought this for my daughter who is entering 12 th grade. She made what she wanted the FIRST time she took the ACT. Now she can get the scholarship she wanted!

I bought this book in order to practice for the ACT, since I found no other books whatsoever that offer that many whole tests. The problem is that the level of the tests in McGraw-Hill's is way below the level of the real ACT. I also practiced using Barron's ACT book and Kaplan's ACT computer program, both had very challenging practice tests, some even harder than the real ACT. If you are abundant in time and want to practice more, get the book, because in any case it's more practice. Otherwise, it's just a waste of time and money; the questions are way too easy than the real thing, and it might misguide you.

I highly recommend this book to anyone preparing for the ACT! The practice tests are spot on! Thanks to this book, along with others from Mcgraw-Hill, my son will be able to get into the college of his choice! Mcgraw-Hill's ACT prep books are by far the best on the market!
