Just finished second semester general chemistry ( 6 week course) I thought I was going to pull every hair out of my head trying to get an A, and would have been VERY dissapointed with a 'B'. Needless to say, I am a very happy camper, and will now proceed to the corner store for the 6 pack of brew I had to avoid all summer, ( yess it is 9:40 AM) bottoms up!!!
