I realize no one has taken both courses since they are antirequisites but I'm having trouble choosing between the two. Psych 3GG3 sounds slightly more interesting but is it much harder? I've taken Social Psych so I'm familiar with Dr. Ostovich's style for 2AA3. Also why does 3GG3 have so many more prereqs...

Any opinions on the two?

I took 2AA3 in Fall 2011 and I found it a lot easier than 2C03 with Ostovich, which I took the semester after. I also found her testing in 2AA3 much easier than 2C03. If I were you I'd just take 2AA3 instead of 3GG3 because it may be a little easier considering it's a second year course.

I think there is one course about development during infancy which only takes pre-req from 3GG3.... You'd have to look at upper year developmental psych courses and see which one is accepted if u are interested in taking such courses afterwards/
