<p>I live in Israel and we don't study logs, vectors and regression till next year. (I'm taking the mathIIC on May 5th). Is it really important to know these topics? Approximately, how many questions are asked about these topics? Should I study them on my own?</p>
<p>I'm practicing for the test with Kaplan. I just did the first test and got 720. Are the Kaplan tests considred easier than the real tests? I ordered the Barron's book for math. Are the tests there harder? Does this book cover the topics I mentioned above?</p>
<p>There are few log/vector questions on each exam - not sure exactly how many. It'll be a good idea to study them, since these few questions could possibly change ur score significantly. You could study them on your own - the concept is not terribly difficult.</p>
<p>Kaplan's Math IIC tests tend to be a little easier than the real tests, while Barron's tests tend to be more difficult. Barron's tests are significantly more difficult than the Kaplan tests, so it'll be a good idea to "overprepare" with Barrons. I'm pretty sure that Barrons covers logs/vectors.</p>
<p>The regression questions on the IIC exam are terribly easy, trust me. No real regression theory or anything, it more or less just looks like any other algebra problem. (At least, that was the way it was on the test I took -- I didn't even realise it was a regression problem, at first.) Don't worry about that, but do work on logs/vectors -- they do matter, and they do show up a fair bit.</p>
<p>And yes, 'overprepare' with Barron's if you can. It's comparatively difficult, but worth it.</p>
<p>I'd third (is that even linguistically permissible?) what Noldo and pyang said.</p>
<p>Barron's is v. good. If you can score at around 750 or greater with Barron's then you'll be able to aim for an 800 with ease. The problem with Math II's time, so do a lot of practice tests and increase your speed.</p>
