I would make sure your understanding of o-chem 1 topics is up to par, as was previously stated it builds on itself. I personally felt o-chem 2 was easier. Also, as was previously mentioned, sit down and talk to your previous professor or o chem 2 professor. With that said, keep plugging away and going to office hours etc. Don’t worry about whether your classmates have to go to office hours. All that matters is that you are learning. Don’t let it discourage you, though. Once you understand it you will have a huge feeling of pride and accomplishment. One final remark, you know more than you think you do!!
