Our school did an informal study that showed students did about the same whether or not they took Kaplan. For students that were performing below average during the school year, taking Kaplan did not "make up" for what was lacking to begin with. So if someone is looking to use Kaplan as a review souce, that is fine. If you are looking to use Kaplan to smoke the boards, you are going to have to do a lot more outside prep as well. I haven't taken the boards yet, but I am using Kaplan as one of my resources. The reviews have been excellent so far, but I see where there are a few gaps, so I plan to supplement the course with other material.
my friend took the live lectures, i don't remember the 3digit score, but the 2 digit was 84. she loved the classes but was dissappointed with the score. I think she could've done just as well w/o the classes.
