I guess it depends on how your class is structured and what you covered, but i thought the hardest part of orgo for me was remembering all of the reactions (I just took my orgo 2 final... where there was at least another 20 reactions we had to learn)... so to help me study for both classes I had made a study sheet with what I wanted to make (ie: alcohol) what you would need (ie: alkene), what reagent you would need (ie: H2O/H2SO4) , write out an example, and then what the regiochemistry (ie: markovnikov addition) and the steriochemisty (ie:none/cis/trans) would be..
I did this on a front and back of a piece of paper... and (yes this is crazy I guess, but between working fulltime and part time and taking 3 classes, time for me was scarce) every morning when I would shower I would stick that paper into a ziplock bag and then stick the bag to the wet shower wall and would get in a good 20 minutes of studying every morning... and then just take that paper with me everywhere else I went (similiar to when I had to memorize all the amino acids, kreb cycle, gluconeogenesis, etc for biochem) and whenever I had a free minute or two, just keep reviewing all of those reactions... Flash cards would work as well, but then my little shower study technique wouldnt work 🙂
I also made great friends with my model kit which helped a lot with those Newman projections (I think thats what they were called...) 🙂
I wish you luck!!
