@miriam98 - We have a couple of technical institutes in our community.
I know a little about technician courses of study, and you’re right; they’re not as heavy on the math and sciences as the full fledged college degrees.
They focus mainly on the math that is specifically relevant to your course of study. I’d be surprised if a civil engineering technician even needed calculus of any sort.
I think this would be an ideal profession for someone who was middle of the road technical; they weren’t too left brained or too right brained, but they enjoyed designing things and were comfortable with drawing tools.
I could even see someone who started out as a graphic designer later becoming a civil engineering technician, assuming that he or she had a technical bent.
