<p>I am an upcoming junior that will be taking normal chemistry. Last year in my sophomore year, I took normal Bio. Should I self-study with a good SAT Subject test chemistry book during my junior year, or should I wait until next summer to study for the Bio SAT Subject test?</p>
<p>Whatever you’re better at; try a few practice tests to find out.
Personally, I’d do Chemistry since it’s more about understanding and less about memorization.</p>
<p>It depends on which subject you’re better at. I’ve heard that Chemistry is a bit harder, since I think it is a bit harder to study for. If you’re better at understanding concepts and prefer Chemistry, take Chemistry. If you’re good at memorization, then take Biology.</p>
<p>Or both :D</p>
