Mum said when I turned 18, no more pocket money. So I got a Saturday job 3 months before my A-Levels: bad idea. But they did pay for driving lessons and tests when I was 17.

With DS, he will be given money until he leaves full-time education. If he also gets a part-time job, it will be grade-dependant. BTW, it's not chore-related. He's expected to do chores now for no money so I don't want a back-dated bill!
