I used neuroprep.com for three years. It was nice as an overall review. It wasn't so much a RITE-specific boost as a general review more geared for the boards. It was expensive. It was convenient with it's Q&A style and online access.
I didn't try your other site.
Best single board review in my opinion is Neurology Board Review by Mowzoon (exhaustively comprehensive though), and a nice compromise is Borsody's Comprehensive Board Review in Neurology. People here seem to often recommend Laughing Your Way to Passing the Neurology Boards. I never got that last one.
Now working on my third year in private practice, I can say that I think that those RITE exams were jokes. In residency, I did well on them every year. Our attendings formulated opinions about our abilities based on our RITE performance. I now think this is a mistake, but I suspect no one is interested in that opinion in academia. The tests are far too concerned with minutiae. Without a doubt, the best way to study for them is to use old RITE exams. However, in my opinion the board review books (and neuroprep) were actually more helpful in the long run because they are more focused on actually teaching you the basics of neurology instead of much esoterica. So it depends on you. Do you want to rock the RITE for the sake of impressing your PD, or do you want to be getting in shape for the actual board exam? Either way, studying any of this stuff will make you stronger. Good luck on the test.
