There are 3 reasons why this class hurts.
First of all, duriing the semester, I'm taking the same math courses as my roommate. I consistently kicked his ass on every exam. Not to say that he's bad at math, I was just better. It's a high 80 vs 90 thing.
Right now, I'm taking Calc 3 in the summer. I've come to find that calc 3 is a much harder course in the summer. The exams are no longer multiple choice, and my TA likes to get creative with the questions (aka make them harder). Also, the averages, which are normally around 40-50 from what I heard during the regular fall and spring semester.. are now 70s. So not only are the exams harder.. the averages are higher too. The curves are worse. We get double the homework. And a quiz each week that's worth 1/6th of an exam.
Now the part about my roommate. We're somewhat competitive when it comes to math. During the summer, he took calc 3 for a friend of his (don't ask me how or where). He didn't do tremendous either, but he still pulled a B. So now when he takes calc 3 during the fall, he's going to know everything and probably get an A. There will be no end to the gloating, I can tell you that.
The third reason why getting a B sucks is... if I get a B, i'll most likely be a borderline case. But the thing about getting a B is... if I wanted to get a B from the start, I could have done that working half as hard as I did because the A range is small but the B range is tremendous. Ahhhh, head hurts
