Best Book for ACT?

<p>Well guys, im taking the SAT on october 8th, and after that I'm planning to take the ACT oct 22nd, I have never in my life taken a practice ACT test, nor do I even know the format of the test. I went to barnes and nobles today and there were primarily 3 books that seemed helpful on the ACT and strategies in getting a good ACT score, (my SAT practice scores are 2100~, but for some reason I can't count on that for sure, and since people say if you are not the best at the SAT, you will fare better at the ACT). The three books were, Barrons, Princeton Review, and the Actual ACT book made by the makers. Which one should I buy, in other words, which one is MOST helpful in learning the concepts (I hear much of the math is different than SAT math, and of course there's a science section) and getting the best possible score?</p>

<p>bump please</p>

<p>someone please answer this question, I have to buy the book today and sign up by tuesday in order to take the test oct 22nd =/</p>

<p>Personally, I liked the Actual ACT book (the red one) made by the makers. The practice tests definitely helped me.</p>
