<p>im going to take sat II chem and Sat II math 2C in my junior year. how much do i need to spend on these subjects? half year? (im going to take AP chem and pre calculus in my junior year,and im just a sophmore.)</p>
<p>well, if you’re doing the material in class, then I’d say buckle down and study hard 2 months before the test</p>
<p>It depends on how well you know both the material and the test.</p>
<p>If you’re doing well, I’d say start studying in late February/early March and take the Chem one in May (since you’re taking the AP test then), and then take Math in June.</p>
