I also found MedRevu to be a waste of money and time.
A couple of people told me to do Kaplan's Qbank. That was the best money I've spent. Having taken the exam today, I can assure you the Kaplan questions are like what you'll get on the test. The MedRevu questions weren't as close to Kaplan at recreating the test environment.
The things I like about Kaplan: A lot of power in creating tests (only disciplines you want, organ systems, etc.), realistic about what the test questions on the real deal is like, reliable access (never got a server busy error!), and the questions were detailed. Don't be fooled by the micro questions on Kaplan. I frequently got A-J (I think I even got an A-L!) answer choices on my micro questions.
MedRevu is overly nitpicky with questions, and it doesn't give you the long vinettes that Kaplan does.
My suggestion: Go with Qbank. You won't regret it!
