The level of this specialty is at a lower level of electrical engineering and most of the courses are easy if you can understand a few concepts of algebra and geometry.The physics from what I have seen is at a highschool level(things like F=ma,a=Δv/Δt,v=Δx/Δt,F=kqQ/r^2).

My question is:,,Can you restart everything you skipped learning during gymnasium/highschool and relearn them in college''?

I already wasted most of my time with homeworks and lessons and I don't want to spend 4 more years for a degree which won't help me a lot.
