<p>Well, next year I'll be a sophmore and will be taking AP Bio. Can/should I take the Biology M subject test sophmore year and then the Chem subject test and the regular SAT in my Junior year, or should I leave it all for on year? Thanks!</p>
<p>Yeah, you can take the tests anytime you want, and still have it count for college. I took the Bio M my sophomore year too, and took/am taking the SAT and SAT Chem my junior year.</p>
<p>You’re fine.</p>
<p>You can take it earlier, and I would highly recommend doing so. I am now ending my junior year and completely stuck as far as which SAT IIs to take. Science especially is one a lot of people take earlier, upon completion of the course. You could take it in May so that you can study for the AP exam and SAT simultaneously.</p>
