My youngest was mostly tutored and homeschooled, growing up in multiple locations overseas. He got into university at 13, did the 2 year undergrad. requirements and quit. He said it was all B.S. I had no problems with that. Ironically, the professors extolled how conservative they actually were during orientation, though they seem to be out of touch with what that means anymore.
I would encourage you to talk with your son about his plans for the future. There are many occupations that don’t require a degree, from truck driving to mechanic and other “trades,” to business person, writer and other occupations where you show your stuff in another way. Some occupations, such as engineer and medical doctor, require degrees (and possibly the specialized knowledge encompassed by those degrees). So, the degree is part of the price you pay. If I’m correct in reading what you wrote, you son has tremendous potential, but maybe isn’t motivated to go down a pre-defined route. He may also be discovering that he is smarter than other people older than he is, and in certain positions of authority. Again, if I am correct, you should see if you can help your son use his gifts to advantage, and not let them become his downfall. I have seen maybe a dozen persons who let their gifts undo them. Hey, if I’m out to lunch, I apologize for taking your time.
