In law school, your grade is usually determined by your performance on a single test.
However, this class was Writing and Research, and like most first year classes, went for 2 semesters. I got an A- first semester, and got a C second semester. The grade was based on a series of papers. I'm not one to blame others for my academic failings, and I did slack off a bit during the second semester of that class.
However, a large number of people in that class saw their grades reversed - people who did really well the first semester did poorly the next semester, and vice versa, and there were some pretty loud rumors that the professor graded a little arbitrarily.
In college, I always got good grades on papers without even trying, and I saw myself as more of a paper person than a test person.
However, in law school, your final exams are basically papers with a short time limit, which I think is why I do well.
Also, rather than simply regurgitating what you were taught in class, as you usually have to do in college, you're actually expected to think in law school. Most exams consist of a fact pattern, 1-2 pages long, and you're expected to explain the legal situation, by applying the law to the facts.
One of my professors put it pretty well: You get no points for knowing the law. It's simply assumed that you know the law. It's your ability to understand and apply the law that is tested.

I'm glad I don't go to whatever college you went to...
