I’m going to be a senior in high school and I was wondering if I should take calculus at a community college and at the same time take pre cal at my high school. I want to become a computer engineer and I know you need a strong background of math for it. I can’t take pre cal during summer because I’m taking computers, health, and economics as a requirement of my school.
Take calculus at the SAME time as precalc?? That’s not what “pre” means. 
Would not advise it…
No! You’re going to drown in a water polo match if you don’t learn to swim first.
