Hmm I can't work out how you can do the two semesters of biology along with six level 3 subjects you need for your course. I'm assuming you're already in first year, so unless you drop calc 2 for a breadth subject, I can't see any way personally. Only way I can see, would be to overload a subject. I'd ask the student centre if there's anything that can be done.
Year 2:
S1: Psych Core, Psych Core, Biochemistry and Molecular Biology, Biol 1
S2: Psych Core, Psych Core, Biol 2, Breadth
Year 3:
S1: Psych Core, Psych Elective, Physiology, Anatomy
S1: Psych Core, Psych Elective, level 3 science, level 3 science
You need to do another breadth subject, which I only see you being able to do in this semester, or if you're allowed to overload.
I could obviously have missing something, being me.
EDIT: From what I remember, the requirements for BSc are (a subject is usually 12.5 points)
Minimum of 62.5 science points level 1, 62.5 points at level 2 and 75 points at level 3.
Minimum of 50 points of breadth, including 12.5 points of level 2-3 breadth
Maximum of 125 points of level 1 (10 subjects)
And for a major in Psychology;
50 points at level 3, 25 points core, 25 points elective.
But double check the handbook, cause there's probably a mistake in there somewhere.
