(disclaimer: i'm a physicist with a PhD) in case you do in comparison to math, the two chemistry and physics would be no longer common for you. Biology, on the different hand, it an incredible kind of memorization with no great kind of order or sense to it. I took AP biology first in severe college. Hated it. Hated my instructor. Hated the smells. Hated the yuk. Then I took AP Chemistry. enjoyed it! i like looking at issues replace. It grow to be like magic. Then I took AP Physics. harder than Chemistry, in spite of the shown fact that it appealed to my sense of order. there are basically some rules to earnings, they do no longer replace, and that they stick to to each little thing!
