If you want my opinion, forget about the courses. A better plan is to buy both the TPR and Kaplan books, read both of them, and do the practice problems. The best thing you can do is to work on the AAMC tests. Neither the Kaplan nor the TPR tests are very authentic, compared to the actual MCATs.
A course is only useful if you can't study independently, and need some focus. If you can study independently, then it's just a waste of a lot of money. If you do it on your own, you can focus on the areas you really need help in. You can't do that with a course.
But, that's just my opinion. Good luck!
