Take this professor! She is very funny and engaging, and the material itself is pretty doable. You need the textbook because there is some material that she doesn't discuss in lecture but tests on. Also, so doesn't use powerpoints so you need to take good notes. Whenever she draws diagrams or makes lists/tables for things, WRITE THEM DOWN. Her tests are very recall based, in that she'll ask questions like "list 5 symptoms of [insert drug] withdrawal" or "what are the peripheral effects of [insert drug]". As a study guide I made spreadsheets with name of drug, category of drug, mechanism(s) of action, central effects, peripheral effects, long term effects, withdrawal symptoms, etc etc for every single drug we talked about in lecture or was discussed in the textbook. This covered about 95% of her test materials and ended up being very helpful! The paper/presentation was easy because it could be anything related to a drug. Topics people had ranged from the history of opium, to LSD and rock music, to The Wire and heroin. Just have fun with it!
