well, i took the verbal edge it this past summer, cause i didn't want to shell out the money for the entire course (and because i was confident enough in all other sections). I used all of kaplan's practice tests (probably around 30 of them), studied their approach to VR, but i also forced myself to do a tremendous amount of boring intellectual reading on my own, for the entire summer.
However - i most of the people taking the verbal edge course were also taking the full kaplan mcat course, cause they either had ESL, or were just plain bad at reading. This course WILL NOT, i repeat, WILL NOT help you read better or understand better, but it will show you some useful tips, and useful methods for tackling VR. If your english is already crappy, or if you can't read well, this course isn't gonna help you do well, but at least you won't get a 3.
I found that the course probably helped me out for about 10-15 questions, honing my reasoning skills in deciding between two answers, and focusing my attention on certain key ideas while i was reading the passages. In the end, I boosted my score three points to a 10 on the VR
D), for my second (and final) time writing the bloody test.
my 2 cents.
