What are my chances?

I am a senior with a 3.76 (hopefully a 3.80 or more by the end of the year) and am planning on applying to the university of Toronto and Mcgill Economics. My sat score is a 1170 (on the new scale) but I’m planning to reach 1200 and i have 3 AP classes and got a 4 on one of my AP exams (the other 2 come out later this year). What are my chances of getting in?

Assuming you are American, here are the minimum requirements for McGill:

Economics is under Arts and the minimum SAT requires is 1240 on the old scale. You also need two SAT II’s.
the minimum requirements are not flexible and meeting them does not guarantee acceptance.
