If I go to Indiana, I'll be doing the Summer Start, which begins in July and runs for about 5 weeks. You take just crim law, so you get to learn how to read a case, create an outline, deal with the socratic method all without the pressure of taking 4 or 5 classes. I'm positive it will be much more beneficial than a regular law school prep course. A similar program helped me immensely in undergrad, and my tour guide at IU did the program and he said it was enourmously helpful. The only thing is, if you screw it up, then you're start at a disadvantage rather than with a leg up. But you'll know exactly what the reading is like, how class discussion works (although all profs are different), and most importantly, what an exam is like. However, it is much more expensive (paying for 4 credit hours), loans and scholarships might not cover it, and you have to find housing for an extra month.
