<p>I've been using the Princeton Review's "Cracking the ACT", and the math section seems to contain information that I've never seen on the real ACT practice tests...It goes over logarithms(which it does mention barely ever come up), the amplitude and period of some Trig. thing, and other things. Here's my question. Does anyone else find that some of the material covered in this book isn't on the ACT at all? Thanks...</p>
<p>There’s usually like 1 or two problems that deal with anything as advanced as logs. I wouldn’t worry too much about it. For the most part the math is pretty basic, like stuff you would have learned by the time you were halfway done with Algebra 2. A good strategy is to use guess and check with answer C since all the answers are in numerical order. This eliminates half the possibilities even if C is wrong. The math is simple stuff, the rest you can guess and check on if need be.</p>
