What is the best book to prepare for the ACT?

<p>I currently have the Barron's ACT 17th Edition book, but I've heard that their practice tests are harder than the actual ACT. That can also help though since you'll be overly prepared for the ACT so taking it would be a breeze. I've also heard that Barron's study strategies aren't that good. I've heard that The Princeton Review and The Real ACT are good books as well. Specifically, what book is the best for ACT preparation? And also which book is the best when it comes to practice tests? I want to have a book for both so I can be well prepared. I specifically need a book with a good preparation for math and science since my lowest scores came from this area. I'm only in 10th grade so I haven't learned everything on the math section of the ACT, but what book will help me to learn those things by myself? My goal is by the summer or beginning of next school year to make a 33, or even a 36, on the ACT. Thanks :)</p>
