In the entire third year I didn't go to any morning lectures. None. I think I went to a total of about 15 lectures all year long. We had a get together group now and again (once a week I think) that was mandatory of about 5 students and a lecturer to see how things were going, and I got a note after a while (about 4 months) to say basically unless I was dead then I had better turn up otherwise I was getting kicked out of Uni. Extra sleep could be got from the few lectures I did attend. For third year final exams I think the most I revised (in total for the whole year) was about 2 hours the night before (after a few pints at the local bar) for one exam I was worried about (Robotics I believe). I would be at a bar, nightclub, or some party pretty much every night of the year. Basically I seriously thought I was in a movie or something. Honestly I was surprised when we had to actually start going to lectures, and really was a bit gutted (in my alcohol soaked mind) that there was no locker lined corridors like out of Fame or somesuch American college movie

And I'm totally not making that up.
So yeah, by avoiding any sort of work at all I managed to fit in a healthy party lifestyle and lots of hobbyist coding.

Of course I have always *loved* programming, so it wasn't exactly I was bored, I just love doing it. Always have. That's why I still love my job (after 17 years).
Actually I wish I had been a bit more into low level code at the time. Main stuff I did was STOS as it was the quickest way to get the best results IMHO. But a mate of mine (Mathematics and Comp Sci) was always dipping into Assembly and the like. A few times when we were all getting drunk and messing about with our STOS and AMOS creations he would be in the background knocking out some cool Assembler raster routines (think of the demos you used to get) and the like. They were cool, but it was like totally over our heads and getting plastered and birds was the name of the game (and the odd DM clone). Didn't do anything to understand what he was doing. He's now a director at EA in San Fransisco and has worked on a load of top games. Nice!
Ah, with the amount of hobby coding I can get done these days I totally miss college days. Don't get me wrong I wouldn't swap my life now for anything, but just in terms of game programming those days were golden. The amount I could get done now (esp considering I don't drink much anymore) is just unbelievable with that amount of time! Seriously missed the boat with bedroom coding in the 80s and early 90s!
