So remember in nursing school when the instructors suggested in the first semester that you get an NCLEX study book and start answering questions from the get go, and continue to answer the questions throughout the program as a study aid/review? (Did everyone else's instructors suggest that? Maybe just where I went to school, I don't know. But anyway, I did it.)

I'm curious if this is also recommended for CRNA school? Would it be of benefit to buy any of this stuff early to study and review throughout the program? Or is it something that is best left til the end of the program as review?
