I got banned a little later (in the 90s) for writing a QBasic "chat app" that worked across the school network by way of a public NetWare shared drive. I didn't even take IT as a GCSE option because having arguments with teachers who thought a PC's base unit was "a CPU" didn't seem worth it, and my disdain for "IT" (as opposed to software engineering) unfairly remains to this day :-D
