Chances of Admission

WIth 750 (Maths), 720 (chem) and 700 (physics) in SAT 2 and 92% in Cbse Boards, what are my chances of getting into Queens, McMaster, university of waterloo or university of Toronto ?
In which of them do I have a chance for an engineering course?

Your chances are good. Canadian universities don’t look at SAT 2 scores though. Engineering is probably the most competitive program to get into at Canadian universities. Each university might possibly ask for additional information in addition to your test scores. If your first language is not English (ie you don’t speak English at home or your school doesn’t teach in English), you will likely have to take the TOEFL or similar.
