Things you should and shouldn't learn at school

When I was at school I learnt many things that had nothing to do with functioning in the real world and didn't learn many of the essentials, practical things like learning how to change a car battery, fix a light switch or a toilet cistern. Things like filling in your tax returns would be a whole lot more useful than learning which King got an arrow in his eye.
