I heard from COSGP rep. that it would be slightly more than 400, but will, like the USMLE, include more pictures. Although I could be mistaken... I know that for the first run with COMLEX I will have less selection of test dates in contrast to the USMLE, however as they get more used to proctoring the exam, this will change. They also have to certify your school or an area near you to take the exam, probably a prometrix center, similar to the USMLE. For those that took the test study, they did mention that there were some pictures/slides/radiographs on the exam. Ultimately, the 2008 classes will be the guinea pigs for this project.
