<p>Next year (junior year), I'll be taking precalc and I am definitely going to take the Math 2 SAT II sometime at the end of junior year. I want to take it in May instead of June but I'm afraid that in that one month, I might learn a lot of stuff in precalc that is needed for the exam. Will one month really make such a difference?</p>
<p>I don’t think a month will make very much a difference.</p>
<p>One month won’t make much of a difference. Buy a prep book and study the concepts on your won to make sure you understand everything, but don’t freak out about the one month of missed instruction in may. If your school’s anything like mine, May isn’t the most productive time of the year (in terms of learning) what with IB (or AP) tests and finals.</p>
<p>Sign up for May and June.</p>
