Yes, I did mean high school. And UGH indeed! I made it all of one semester. Schools are indeed dumbed down considerably from when I went to school eons ago.
I thought about teaching in a community college - beginning engineering courses or software. BUT again, lots of typing required for the programming courses. But it ‘might’ be a better crowd than HS. These days in Mexifornia, though, with all the anchor babies going to school on grants, who knows?
I know some community colleges (especially those that act as feeders to a four-year college) would have an engineering programming course. After you develop the course, you may be able to cut the typing by reusing your examples.
Good luck and the third time’s the charm!
