However, if you are aiming for a really high score, I would just take the heaviest, most extensive prep that the CD offers.

The Kaplan CD set I used when I took the test is probably not available anymore, especially since the SAT changed, but here is a study set that comes with a CD and a book:

Here is another set of CD and also gives you test prep for the ACT, which is a test that you might want to consider taking since colleges seem to be noticing it more and more these days:

They are both about $35.

Personally I like the computer based preps, because you are timed much more accurately on the practice tests. But regular books are also good to use, especially when you get tired of staring at a computer screen.

It’s important to start studying for the test as soon as possible, that is, give yourself plenty of time. I studied for the SAT about two years in advance, basically for a few hours on the weekends, as I was still busy with schoolwork during weekdays. It really paid off as I got a 790 on the verbal section.

Good luck and study hard!
