I took the entire exam krackers extra and comprehensive course. Truthfully, i felt that the extra course was not worth the extra thousand dollars. It was nice to have Jordan Zaretsky the cofounder of exam krackers teach nine lectures, but a thousand dollars for 5 extra bucks (retail value of 150) and nine classes was a little obsurd. The extra course has around eight people in a class, it is not semiprivate tutoring as i expected from their course description.
I do believe that the comprehensive course is a tremendous value as you get just the right amount of classtime and their great books (u can actually buth them on amazon). I had two wonderful instructors that really knew their stuff and how to simplify the science. The best thing about Ek is that after eveyr practice test you get a DVD of jordan and JOn (founders of EK) reviewing every science question. They dvds are very educational and moderately funny. And one great thing about EK is that you get to evaluate your instructors weekly and they will fire an instructor almost immediately if he recieve poor reviews, so it is likely that you will get a very good instructor and if not he/ she will be replaced quickly.
Good luck,
Dave
