Admission HELP

Hi, I live in the province of Alberta (in Canada), and was wondering what would be my chances for getting in U of T Life sciences at St. George and Mississauga.

Grade 11:
Biology 20 IB - 85%
Chemistry 20IB - 76%
English 20 - 75%
Maths 30-1 (second time mark) - 84%
Physics 20 - 81%

Grade 12 (so far in semestered) :
Chemistry 30-1 - 95%
Physics 30-1 - 81%
Science 30 - 97%

Also, I was wondering what I would apply with if I haven’t yet taken the course. Would I apply with: Grade 11 English 20-1, Math 30-1 (pre req), Grade 12 Chemistry 30-1, Grade 11 Biology 20 IB and Science 30, because then I have a 87.2% average. Also, I was wondering if any EC, like volunteering, could help my application. Also would my grade 11 IB classes help that they are IB, or would it not make a difference between my regular classes. If you could tell my my chances of making Life Sciences at St. George and Mississsaga, that would be great, Thanks!
