I'm going into second year Honours Psych. I took 12U Biology in high
school, and took Biology 1A03 as my prerequisite to gain acceptance
into the psych program. Upon looking at the 08/09 course calendar, I
noticed that in order to take Psych 2TT3 (a required course for me), I
needed either Biology 1M03 or Biology 1P03. I was hoping for seats to
open for 1M03 last night, but, contrary to what I was told from the
Psychology department, they did not.

I NEED to take this course in order to get into one of my other psych courses. What do I do? Any replies are greatly appreciated.

haha! nevermind

It seems like your problem was fixed, but for others who are stuck needing (for your major) a course that is full, call the department that the course is offered under - Science, Humanites, ect. They can give you permission to register in the course, even if they say it is full, especially for first year courses. (They keep a few spots open for exactly this purpose)
