I tutor SAT/ACT to little high school bastards. No, actually, they are great kids and I enjoy the work. There isn't much to tutoring those tests, because most of these kids just have poor test-taking skills (don't know process of elimination well, don't know guessing strategies), and you just basically baby sit them through a bunch of passages and get em primed for the real thing.
I went through SCORE! Prep, it's a branch of Kaplan, but it is one on one tutoring... payed 15-20/hr ...
Or, since you've made it through med school, you could probably tutor MCATs and make decent money, but then you have to deal with that awful breed - the pre-med...
Have fun
