I'm not a good test taker

The calculus exam is a week from today, which makes me nervous. Janice said yesterday in class, “If you’ve done the homework problems, then you should be fine on the test. It’s nothing too weird or out-there.”

That’s reassuring, because yes, I have done every homework problem so far and have missed only one point in the class in three weeks. I just worry about being able to do the exam in a reasonable amount of time, because I’m quite slow and very precise and careful when I do calculus problems.
