I took both organic I and II from UNE just last year (finished II in November). Within 2 weeks of taking the organic I final, they changed the whole test because one of my fellow "classmates" kept talking about exchanging quiz answers to compile a database of questions- DO NOT GET suckered into this! The final, for me at least, was nothing like most of the quiz questions were, definitely not identical enough to count on them to help you pass.
I ended up with a C in the course, and honestly, was happy with it~ if you do have to take organic II, it was a different instructor and I scored an A-.
Good luck and FYI- I am starting a CRNA program in 4 weeks, so a C shouldn't keep you out.
