Teenage son refuses to do homework

[Clodbod]

My 15 year old son gets all homework online through a system called senaca learning he never does his homework,l have confiscated his allowance,he has Mock GCSE exams coming up lm somewhat to blame as l used to work late abd lm parenting alone so he was lef t his own devices,any ideas?

Get him at the table to eat
Have a how was your day chat
Get laptop out sit and do homework 'together'
Seneca is alright it could be a lot worse

At that age I don't get involved in their school work. They're the ones that face the consequences, be it detention (unless it's an after school one and you have to pick them up!) or poor grades.
We did have a routine though, so it was chill time until dinner, then I'd expect them to do homework after dinner. If you provide the time and space, the rest is up to them.

Let him suffer the consequences.

What does the school do when homework is missed?

My ds was a bit lax with homework and then he seemed to change and I noticed that he was always doing it on time. I told him I'd noticed and was really happy with the change and he said he'd just got so fed up of my nagging he'd rather just do it 😂

Best thing you can do is leave him to his own devices and let him fail his mocks. That’s what mocks are for. Let him learn the hard way what is required. If you badger him into revising now and he passes, his behaviour won’t change and you’ll be badgering him next year too.
