Getting back on track though.. you are better off just gettimg an instructor position. It would require a lot of overhead to establish a training center.
I think milburn is guiding you in the right direction with business management. However with that in mind, my wife just finished her degree and it required math. Statistics, accounting, and calculus.
I know any degree for general education will require you to take a placement test and finish math courses. Certain degrees require extra and business is one of them.
A good friend of mine just finished his Info. Tech. Degree with an emphasis in networking and he just had remedial math courses.
If milburn teaches here Cali he can speak more on it. I know the private institutions like ITT, wyotech, etc are easy and dont really do math but thise degrees dont really hold value.
Idea.. download ASU catalog and it will break down all the required courses for the different degrees. Beside those main major courses you just need to complete the general education.
