Math choices

I kind of didn't learn too much from the presentation...but, I learned that there's different paths with math for your future career. I know for sure that I want to be a recording engineer or just a musician. Both of those career choices don't need very many requirements. All you need to get is your grade 12 and you could be a recording engineer. Math requirements is your grade 10 math. I don't need fancy math classes so basically, It doesn't matter what am path that I choose. I'm thinking that I'm going to go in pre-calculus. That decision isn't final yet. I still have awhile to decide.
