I am a science student and I was wondering when do we find out if we got into the 2nd year programs that we applied to. Also, where do we go to check this? or do they send you an email, etc.?

It will appear on you grade reports when all your grades have been released by the registrar's office.
It will appear something like this.

Eligible for:

Bsc/ Biochemistry
HBsc/Biology

then when you go to choose you classes for next year, it'll show a screen where you pick what program you want to enroll in
