Post-AP Classes

But how hard would you say Linear Algebra or Multivariable Calculus is? My hope is to take four post APs Senior Year as DE classes, which would give me more time to work on college applications, interviews, etc., than if I took all my classes at the high school. However, if something such as Multivariable Calc or Linear Algebra was extremely rigorous or difficult to grasp, I don’t see the advantage of spending my time on it over say, AP Statistics (seeing that I don’t plan on being a STEM major).

The issue is now that I would have to take Pre-Calc over the summer to take AP Calc Junior Year, which would allow me to take an upper math Senior Year. However, as a non-STEM major, are there many valid justifications for all this extra math work?
