Has anyone else ever had the experience of getting really good grades in higher level courses and getting kinda mediocre grades in lower level ones? I think I'm going nuts. I keep getting pretty decent grades in 300-400 level courses but get like low Bs in the 100-200 ones. It annoys the hell out of me. I keep thinking that if I do well in higher courses I should be able to do even better in the freakin' introductory ones. I'm starting to think something is wrong with how I am taking the classes or maybe others have had this happen? Either way, it makes me wonder whether taking a 400 level class is really that much harder than a 200.
