<p>I’m kind of in the same situation. My strengths lie in the maths/sciences, but I did not learn much the 1st semester of chem and physics. I had great second semester teachers. I did not really understand physics all too well, but chem was 9th grade while physics was 10th. I am going to go to the book store soon and check out the prep books and see if that gives me any idea which one would be easier for me. I suggest you go with the one you’re more comfortable with.</p>
