Karim, seriously, no offense but you gotta spend more time doing work than going on SDN. You have a lot of motivation but also realize that SDN is a deadly addiction. You can easily understand chemistry if you clear your mind and think about what the text is saying instead of reading it like a novel. Your time would be better spent focusing almost copmletely understanding the material than just learning how to get the right answers. Read the chapter or go over the notes a couple of times (1x, 2x, 3x usually gets it in the mind for good for me).
My motivation for this class is this 1) A test of my own intelligence...a battle between me and chemistry. So far it's a stalemate, I'm going to rape chemistry like cowgirl (convict guy thread reference) 2) The concepts will be emphasized on the MCATS. What I do not learn now only hurts me in the next 2 years when I have to take them. 3) I need to learn this stuff INDEPENDENTLY. Professors are there to help you for the most part in college, but it is you that needs to learn it by yourself for the most part. What happens when you have your own private practice and you don't understand what is happening in a new journal? College shapes you to become independent. You may not see it now, but it really is the key to success in upper level courses. 4) everything is directly applied in physics and organic chemistry.
