Am I cooked??

Hi guys so Im in quite an interesting position... I got accepted yesterday for engineering which is great! But my physics grade is cooking me (I live in Alberta btw) as in it wont be above 70% I can try and not let it drop bellow 60% which I think I can do (Im at a 63%) rn..... but the rest of my grades are 80 plus. So the question is since I cant get it above 70% like Im supposed to... am I cooked??? Will I maintain my offer???

-For reference my grade 11 physics grade I got accepted with was 68% not above 70% yet they made an exception and accepted me because the rest of my grades were high.
