<p>depending on what field you would like to enter/what undergraduate field you are planning on applying as, you may want to take the SAT II Math IIC instead of the IC. I'm not sure what the difference is (for material), but the IIC is more respected by most schools. </p>
<p>Two months is plenty! I took both tests on the same day, studied for a month before, and got an 800 MATH IIC and 760 BIO M. Buy a couple good study books for each test and practice! good luck!</p>
<p>unless you're very bad at the SAT or desperately need a good score, 90 min per day is a bit superfluous, don't you think?</p>
<p>I'm not judging you, I think it's quite admirable. But just remember, those minutes are going to add up and you could be spending them doing something adventurous and EXCITING.</p>
