I seem to remember most lessons being optional most of the time especially after lunch, except Chemistry which was rather fun because we had a mad scientist teacher who used to teach us how to make contact explosives and other fun things, of course being teenage boys we always surprised him with the amount we made. He never seemed to mind us smoking or drinkin g tea in his lessons either pobably becasue he could then as well, although he got a bit snotty if we added any alcohol to teh tea, never understood that. Come to think of it Biology was good because we got to take lots of frogs and other small animal like things apart. Physics was quite a worthwhile subject too although more becasue we got to put things together there.
AH but best of all was sport that was where you got to try to take humans apart, you have no idea how much most little boys enjoy that!
If politics were an honourable profession no self respecting politician would be interested in it.
