<p>Baghdady1989,
I got a 800 in SAT I Math and 800 in SAT II Math IIC
Honestly I would advise you to start off by taking one test from any guide book which details your strengths and weaknesses. After that pick up your weakenesses and go through your Algebra/Geometry/Trigonometry/Precalculus etc Textbooks and go over your weaknesses one by one.
I honestly find this study technique to be of maximum use and I am not a big fan of studying those condensed cram notes from the Barron's, Kaplan etc. Therefore my best advise to you and everyone would be to study a topic one by one instead of just taking a multitude of practice tests. You should take the practice tests to improve your timing but that should come after you have learnt/grasped all your weaknesses and refined your strengths
Good luck</p>
<p>I also got a 780 on the Chemistry and would advise you to study Barron's just for Chemistry and Physics, not for Math IIC.</p>
