coming from an experienced MCAT teacher, TPR materials are more than extensive in covering the material. it just comes to test taking after that. I personally went from a 24 to a 35, but i'm a good test taker. not everyone improves that much, but it's not because they didn't have enough materials. the books give you everything you need, but most people don't learn that material well enough. you need to have it down, and that means preparing months in advance and really knowing it well, not just looking at it once through.
