I waited until punch cards were no longer at use at university, then I switched majors to computer science.
Saw a Hollerith card held up by the professor to show us what they look like, but never used one, nor a key punch machine, nor a card sorter.
Did use a Dec Vax 11/730 for my Pascal homeworh though. With Dec VT102 vacuum tube/valve terminals and a 132 column green bar printer.
