The knowledge needed to win a pub quiz, gameshow or other trivial pursuits
Below is a rough list of the topic categories which, if you can commit them to long term memory, will serve you well in a good ol' pub quiz. There are clever ways to remember many of these things, and as I find them, I'll share them here.
Bodies of Water
British Prime Ministers
Periodic Table of Elements
Planets and Moons
If you know all of the above, then you're always going to do pretty well on a quiz in the UK I'd say.
