Which science subject test's curve is the most lenient?

<p>I'm a sophomore right now and I am not sure what AP science subject(excluding E.S.---slackers!) I should take in junior year. It's important since I'm planning to take one science SAT II after taking the AP test.
I'm taking Physics, but I have a B right now. Physics seems really important and practical, but I just don't get it... I heard someone in CC say he or she took AP Bio in his junior year and had a good result. What do you guys think?</p>

<p>And which SATII science subjects is the most lenient? Is it really Physics?</p>

<p>Yeah, it's really physics. Chemistry is probably second, and then bio but both of those have harsh curves.</p>
