I go to a top ten school, I've always been at the top for english so I wanted to do eng ext 2 (my ext 2 eng teacher is quite strong which is why i wanted to do it). However, I recently made improvements in maths, notably I'm top 25 for the last prelim exam in my grade so now I wanna do math ext 2. My other subjects are chem and phys. Is it worth it to do double ext 2 and either throw eng adv or chem. Also, if i don't do both ext 2 i have to stay in economics so its rly math ext 2 or economics.
