My sole computer class in HS and college was THE class senior year of HS in 1971. We used an acoustic modem to talk to a local university computer, some IBM box. The language was BASIC. Storage space for the school of 3,500 was either 8 or 10KB (not a typo, it really was kilobytes). Anything bigger was written on paper tape at a teletype. I used password protection and could create programs that the teachers could not touch. That said, my entire career has been computer-based. First job was computerized equipment test and data acquisition. After 6 months as lead programmer, my boss asked how much prior experience I had. When I said none, she asked me to never tell that to anyone else and keep up the good work. I saved the company well over $500,000 in testing expenses that year. Since then I have done statistical QA, CAD, FEA and software docs. There were also a few years writing for the trade press.
