I'm starting y10 next school year and i feel like i've been panicking too much about my A-levels, i probably will Major in chem or biochem or something similar, and to go abroad i would need 3 A-levels but i can't think of a third, if i take chem and bio, then taking math would be a death sentence, my math is not that good either way, so i'm stumped.
Also how many (minimum) O-levels would i need to go abroad to go outside Egypt to Canada for example?
