I had just posted this in the wrong thread...I used neuroprep.com and my husband used neuroscalps.com, they are both really good, they have good questions similar to those we saw on the boards. I think overall the boards have easier questions that those you see on these websites. I think these are the main differences between the two:
1. Neuroprep has questions ordered by RITE categories. So if you prepare based on your RITE exams preparation, you may like this better. Neuroscalps has questions ordered by the boards categories.
2. Neuroscalps has video questions that neuroprep does not have.
Good luck!
