I guess I'm in the minority with this opinion, but I thought Ochem II was much easier and different in nature - more about recognizing synthesis steps and a handful of large standard mechanisms, as opposed to being all about bonds and solving many unique cases of "what happens to this molecule in acid" etc. I had a couple friends that worked their butts off for B's in Ochem I that found Ochem II a breeze and got A's.
Professors can be a huge factor as well. My Ochem I prof gave exams with median scores in the 30s and 40s, where scoring well was more about speed and flashes of insight in solving difficult, unique puzzles than study time. Ochem II was scores in the 60s and 70s and studying paid off more because material in the practice would be on the test.
So, ignore the haters, and get that A.
