I need to take 1 year of humanities/social sciences courses for prof school. If I take intor to psych x03 and another psych, does that fill the social science requirement?

Uhm, that's a good question. You can go two ways with a Psych degree, BA or BSc... so technically it's both. But if I were to venture a guess, I would say that it's a science course now... but ask an advisor to be sure. The advisor for Psych responds quickly, just e-mail her.

Better idea is to email the professional school itself.

Generally it doesn't matter how your school is organized, its what the school you're applying to wants.

If you look at the Social Science I list, it's there,
but it falls under the faculty of Science...

I'm pretty sure it counts as a Soc Sci course, if not, I'm in trouble =/ xD

It depends on the school you apply to.
I would call/e-mail someone from the admissions section of the school you're thinking about and ask them.

In terms of medical school - U of T saw psych as a science while Western (I think it was western...) accepted it as a social science.
In my case I was hoping it would work as a social science.
