history: Everyone in my Calc class was stressed out over an exam. A few days before the test, a class mate announced she had made a study guide and would be glad to e-mail anyone a copy. It was because of her that I got a B. I don't know how you are with Calc_comma_ but I can get pretty anxious before an exam.
current: Math has never been my strong suit. I'm more of a history type of person.
next: Me neither! That's why I was amazed when this girl said she had made a study guide and would e-mail us all a copy. I ended up with a B!
