Exams and studying

Exams are coming up shortly, and I have slowly been preparing for them. I just have issues with actually studying, as I never really learned how to study properly. Some people can sit down and study for hours on end and learn the material. My problem is that I get the general idea of things way too quickly, and the specifics have a tendency to bore the daylights out of me, which means that I don’t really want to learn them all that much. They are in the books, so why bother to actually learn them? If I need them, I go look them up in the books, dammit! The key is knowing that those details exist and where to get my hands on them when I need them.
