My best advice is make a review sheet of the reactions, (hydrolysis, oxidation, etc) if your prof hasnt done so. Second, practice, practice, practice. You can sit there and memorize, but organic chemistry is a lot of applying your understanding. You start to notice patterns and realize "oh you use this and this happens".
Most importantly, talk to your professors. They'll give you strategies on how to approach problems.
