I'll give you my overall study progression, which you can probably do in 5 weeks or atleast most of it. I scored 22-22-20, and wish I would have studied a little harder early because the last 2 weeks I seriously crammed.
A few months before the test, I started going through the standard Kaplan book. I read over everything and noted anything that I was unclear on. A good tip to get through material that is boring to you is to set time goals, like get 45 minutes of bio and then take a break. I also liked to study science then PAT then go back to science, because the PAT was kind of fun (I primarily did practice problems for PAT prep). The last few weeks before the test I took the 3 TopScore practice tests, and went over every answer. Anything that I didn't understand 100% I reviewed in Kaplan or wikipedia or whatever. Take as many practice tests as you can because they are probably the best study tool available, but save some for closer to your test. Finally some math advice...practice problems are best here too, but make sure you practice SPEED. There are going to be some formulas you need to remember. However, practicing shortcuts and quick math can help your score as much as anything. For example, if you have an algebra problem you know how to set up, but will take 2 minutes to do, just start plugging in the answers to the original till you find the one that fits. At worst, it takes you just as long, but if the answer is the first or second choice, you just saved a minute. I didn't review a lot of complex math(statistics) and put very little time into trig, but I got a 21 because I was able to answer every question and go back to 1 or 2 problems that I knew would take more time.
