Should I be writing a detailed reason for each question I got wrong in a notebook, so that I can go over it later?
jmugele: I would not revisit the ones I got right. Instead, as I’m taking a test, I’ll mark the ones I’m guessing on or unsure of (I wouldn’t worry about keeping track of time on a test until late in the studying process). That way, even if I get them right, I can still go study them. What I liked to do after a test was immediately study each wrong answer or marked answer to better understand it. Then, I would also keep a log of the topics that I was having trouble with and make a point to go study the topic more. It’s much more useful to know which subjects you need to study more, than to be able to nail a particular question.
QofQuimica: I would recommend reading over the explanations for all questions, even the ones you got right. The reason for this is that WHY you got the question right matters more than the fact that you got it right. (Let’s be honest; we all get multiple choice questions right sometimes out of sheer luck!) While you are studying, you should be concentrating on improving your problem-solving and thinking skills, not on any one particular question or answer. So if you read the explanation and it is along the same lines of what you were thinking while you were taking the test, then you are doing the right thing. On the other hand, if you read the explanation and it is completely different than your own method for arriving at the answer, you should check into whether your method is generally correct or you just happened to luck out that time.
