I'm in Seattle. I used a friend's Kaplan materials the first time I took the test, and I bombed it. I used all of his study materials (I know, unethical, but I was really broke and desperate) but I didn't really dedicate myself to studying. Then I took the PR course and improved my score dramatically. Some of the instructors were really good, and some actually sucked, but I would just go to other instructors' classes in those cases. The good instructors were amazing though, and one even offered an extra review/what now (post-MCAT) session. PR seemed to be much more content review, and that's apparently what I needed. I also spent a TON more time studying, treating it like a full time job since I was just working all weekend.
PR was definitely helpful, but what made the biggest difference was realizing that I couldn't skate through the test like I did school. If you choose to take a class, use it as a skeleton and frame your studying around it.
