I took the Kaplan course and I got a composite score of 95% my first time around. The course was great, but in the end it really comes down to self motivation. I studied about 40-50 hours a week for at least 6 weeks for the test. One thing is for certain; if it is on the PCAT it will be covered in the Kaplan course, but so will a bunch of extra material. In my opinion, the course was worth the $1000. Not because of the actual classroom instruction, although that does help, but because of the all the quiz, online workshops, review tests, and full length mock PCATs. Yes, a $1000 is a lot of money and someone who is very self motivated could do fine by just buying the $50 PCAT book, but the course is still a really good investment. Not to mention, if you don't score as high as you were hoping, you can always talk to the Kaplan people and they are usually very understanding and willing to let you retake the course for the next PCAT for free, although if you thought the course was worthless the first time, it probably won't be much conciliation.
