psych 2d03 and 2f03 are antirequisite of each other.. i think.. since they are both the same thing.
i took psych 2f03.. very intersting course, ullal is good, just makse sure u MEMOrize your slides.. theres no understanding in this course.. since its just random stuff put together.
and for psych 2bo3, read the course handout and do the online quizes.. and u'll do fine
goodluck
