Im I cooked??????

So Im just 2 months into my IBDP program and my classes are HL: AA, Econ, Physics. SL: Chem, french, Lang & Lit and TOK ofc. So im here to say: Im scared, like pretty scared for my future atleast. My bigget threat right now is AAHL. In my first quiz i got a 3 and then in my summative in Series and Arithmetic etc... I got a 3 again, and then for my functions quiz I got a 5! but then when the summative came holy fuck I got screwed over. I feel the Revision village IS WAY EASIER than whatever my teacher gives.

And speaking of my teacher hess a condescending rude person who belittles everyone. So I jsut really want to some tips. Im an aspiring engineer, but math has never been my strong area, except ive always been pretty good at physics. Im worried if I continue my math and maybe physics grades will pull me down. Im trying to get into RMC in canada, and Its a dream college for me since ive always wanted to join the armed forces, but I always wanted to be an engineer. Im worried I might just not be made for math or engineering.

Im a super creative person, I really like math too, its just scary too. I did horrible in my 10th grade math classes and never payed attention untill I had a reality check and managed to get out with a b+ but I felt i seriosuly missed out on alot of the fundamentals.
