On a scale of 1 to 10 (with 10 being the best) my experience with NSU core rotations would probably be an 8.5/10. Overall, I really enjoyed them and I know they have prepared me very well for the boards and residency. The only caveat is that there are very variable clinical location sites where third years complete their core rotations - some are better than others. Choose wisely.
Don't ask me to rate the first two years at NSU.
PM me if you have any specific questions I can help you with.
