>I strongly recommend Calculus because you can do mechanical engineering with it.
Don't do this OP, no one is gonna give you anything extra for being smart or knowing calculus and in best case scenario you just get to solve all trouble because "well you know better".
learn calculus because improving yourself is always good tho.

just keep going. if you struggle with a couple of exercises, do 20. once it settles on your mind it's not so hard, difficulty comes from seeing the triangle on the plane, the fucker is hidden. also take this, don't ask, is magic.

you don't need anything beyond a basic scientific calculator for high school. I bought a cheap copy of a casio SVPAM or something like that for 3€ and that's more than enough. big numbers belong to the office.
