I'm pretty much the polar opposite of Bob.
I enjoy math and science, and grasp most of the concepts very quickly. Most of my daily thought processing is calculated logic, so those subjects are my bread and butter. I've only taken non-calculus based Physics, but I felt as long as I understood the concepts (as in, what formula is used for each type of problem), the class was just "plug and chug".
I've been told that I'm a good writer, but it is the furthest thing from natural. I take an obscene amount of time compared to others to complete my work, which is probably because I'm not particularly creative. If it isn't analytical or pure memorization, I have to devote plenty of time to do well.
