<p>After skimming thru this post, I want to take AP Chem exam so bad. I could not take the ap exam bcoz my school didn’t have enough kids to take that test. I know it sucks, but that is how reality is. I took Chem H last year; I found it easy because you don actually need to memorize a lot stuff. In order to excel in chemistry, you need to learn how to analyze and understand how is formula manipulated to get another formula. For instance, the combined gas law is pv/t, from which u can deviate another three gas laws. As someone mentioned above, khan-academy is pretty useful if you need to reinforce what you have learned from the class. Good luck.</p>
