Should I take Chemistry SAT2?!?!?!?

<p>Hi, this is my first post here! I'm taking 2 SAT2s in a week, Chemistry and Math IC. The math one I feel confident about, since I got a 660 on the first practice test I took, with no particular review, and a few that I got wrong were simply things I never learned that I now know. I will take another practice test or two before the test, just to be sure.</p>

<p>Chemistry, however, I'm not doing so well with. My first practice test in Kaplan was a 630, second was 610, and third (on SparkNotes) was 590. I seem to be getting 20 points worse on each test, despite my attempts at reviewing what I got wrong. Is there any chance of picking up my grades in the week I have before the test? Also, can I cancel the Chemistry one (in advance) and still take Math? Finally, if I screw up on Chemistry, can I request College Board not to send that one?</p>

<p>I may just cancel Chemistry (if I can) because I am taking these tests without a clear plan of what college I want to go to (I am only a sophomore) and I may not go to a college that needs them.</p>

<p>Thanks in advance!!! :)</p>
