I took chemistry my sophmere year of hs...and man was it hard. I think it was hard, not sure I never did any studying. Teacher wasn't the friendlist either...hah, I remember staying after school one day during the start of second semester (where i couldn't understand anything, failed it anyway) and asked her how to do some of these probs. She asked me what was the problem, I told her I was always alseep. Her exact words to me "No sh*t, I can't believe you even have the nerve to show up and tell me that." Well, needless to say I got to spend the last 2 months of school in my friends ceremics class.
