I had this major asshole named Mathis who taught Mechanical Drafting just before CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) came around.
He would load you down with work so you lived behind the drafting board.
Guess what? Mechanical drafting quickly became obsolete.
That is the prob. Most of the Business Dept courses are a total waste of time and not easy. All these theories you will only use if you get employed by IBM.
Best thing for you long term: Math
Algebra until your head explodes. Someone is a math major here. Phoenix I think
I had one class in Calc and that stuff is insane. To do calc you must know algebra inside and out. I actually was getting to my mental capacity after the one required course of calc.
That stuff (calc books) was mostly developed and written by bearded guys 300-400 years ago while on hash when there was nothing to do but drugs and math for "fun" in 1568 or something.
The one thing it teaches you? There are some VERY smart people and many things are possible incl landing on the moon.
