SDN Members don't see this ad. (About Ads) I'm noticing a trend with a lot of my grades where I do a lot better in certain science courses than others in spite of the class average. I was wondering if anyone had any idea as to exactly why this is. The trend goes like this: Bio > O-Chem > Phys > Chem I don't find any of these classes significantly more interesting than the other. It's weird but bio and o-chem feel like they come naturally to me. Phys not so much but with a little bit of practice I find that I can handle myself just fine. When it comes to chem I feel like a total dunce who, despite struggle, is forever stuck in the B range. If anyone here has a better appreciation for what sorts cognition is involved with these classes offering advice is much appreciated.
