Admission chance for intl' students please help meee!!!

Hi guys!
Recently i ve been so nervous about my admission chance…
so here’s the point… i got an ielts score of 7.5 (all subscores above 6.0) and an UW GPA of 3.65-3.7/4.0.
I ve submitted the application and on my way to complete mcgill’s supporting docs… My first choice is Biol Sci.

Do you guys think that i am able to be admitted? Do i take sat 2 tests (maths and biol) to increase my chance?

Thanks a lot!!!
