McGill IB diploma requirements

McGill’s servicepoint seems to be blowing up right now so I’m going to take to the interwebz to see if anyone might have an idea if I might pass the requirements.

I want to apply to McGill for Life sciences but I only took one science.
Here’s my IB breakdown:

41 Overall
38 Subject points
Chemistry HL 7
Math SL 6

Do you think they’ll accept me if I take a supplementary exam for biology or something? Should I even bother?

Here are the IB requirements. for Life sciences you are missing the science requirement.
