should i drop ib & switch schools or just stay at turner?

hii okay so i’m currently at turner fenton in ib and i’ve decided i wanna drop it going into grade 12 bc i got a really bad mark in chem even though i studied SO hard and it just made me realize ib is not worth tanking my average for

also like most ontario unis don’t even care if u did ib, and i already have the study habits from the past 3 years so i feel like i’ll be fine in mainstream.

but now i’m stuck — idk if i should just stay at turner in mainstream or switch schools entirely
like:

• turner mainstream is STILL hard and competitive specially main subjects like bio/chem/math
• i’m not in any clubs or execs bc all the positions go to people’s friends
• other schools(where some of my friends go) are apparently way more chill, easier marking, and easier to get involved

i just want high grades for top 6 + more time for ECs/business/etc bc i’m tryna go the pre-med route.
but it’s the end of july so idk if it’s even too late to transfer or pick courses

has anyone switched out of ib this late? or changed schools before grade 12? would u recommend it??

pls help
