it depended on what you really like, fighting !
if you want to be on a school to becoming an engineer, you have to have a good file a good at physics and maths like "queen07" said (of course you have to be good at others subjects :D) but if you want to take account I think there's two chooses : going to a private school (if you can pay it) or go on public (university or public school if you have) and you have to be good at maths too (statistics especially) but I'm sure you'll handle it ^^

I do not know if my review will help you because I'm not really good at english uhhuh but keep working ! ^^
