<p>Last year in May I took Chem and got a 760 and was somewhat disappointed by the score. I got a 5 on the AP test for chem and am thinking now if I should retake Chem to get a higher score. I haven't look at a prep book since last year however, although chem is my best science. </p>
<p>I've already taken math 2 and am going to take physics in may, should I retake chem? Is it going to be worth it? Is it even going to matter (I heard some selective colleges only require 2 subject tests, is that true)?</p>
