I didn't touch a personal computer until a few years later in a job where we had an Apple II to do some engineering calculations. High school was BASIC using a teletype connected to a local community college--and that was pretty forward looking at the time.

I did take a FORTRAN course in college which people would consider very rudimentary today. This was the textbook :-) https://openlibrary.org/works/OL6795090W/A_Fortran_coloring_...

But I didn't really use a computer to speak of (other than as a text editor in grad school) until I was working--and later got into programming as a hobby.
