What happens if you DON'T continue education after 16?

Just so you know I'm speaking here theoretically, and I do plan on going to sixth form and doing A-Levels.

What happens if you don't go to sixth form or college, or do an apprenticeship, in fact you do nothing? I'm just intrigued to see what will happen, as the law says that you must continue education until you're 18.

I'm asking because my (very stupid) friend is planning on doing this. There's no point convincing her so I'm not asking for advice on how to - I just want to know what will happen.

Thanks.

Edit: No stupid responses and bother to read the OP damn it.

in the uk: if u are not in education or apprenticeships ect your parents get aprox £90 fine a day for everyday you miss and if its over like a month they have to go to court but u yourself don't really get in trouble until all thats done. but u can also work if your not in school. if you worki think its 29 hours or more u can say that and im pretty sure that counts
