David K

how many hours must one devote/wk,? assigned homework? random quizes/mini-tests?

Emma D

Instructor

Hi David - this is a good question.  I have some general advice here.  First, save yourself time in the long run and invest 10 minutes after each class to make flashcards on things like functional groups, reagents, reactions, pKas, etc.  Second, you should plan to do 2 hours of practice for each 1 hour of class (so if you have three 1 hour classes a week, that would mean that you do 6 hours of homework a week).  Finally, as test time comes closer, you want to increase this and add an additional 10 or so hours for midterm preparation and 25 hours for final exam preparation.

Be careful for organic chemistry -- it's a course you cannot cram for.  If you invest short periods of time frequently over the semester you will get more from class and studying and thus save yourself time in the long run.  Topics build on themselves so try and stay on top of things and you will be successful!
