Do you just leave them to get on with it at 6th form college?

I had a nightmare time with dd over gcse's and lack of revision. As it happens she did very well, better than expected. I told her once she was at 6th form she would be on her own. No more lifts to ensure she was on time and no more nagging about work.
However, 4 weeks in I've found out she has been late for one class in particular a few times and is being distracted (by boys) in lessons for this class also. She is late for everything and always has been and she does not seem to care.
I've told her tutor to crack down on her as she doesn't take any notice of me and that she has to take responsibility herself. I tried speaking to her about it but it ended up in a row
I must say she is only at 6th form as they have no choice and have to stay in education.
I should really just let her sort herself out shouldn't I?

Yes, it's up to her to handle it now.

Although at DS' sixth form - parents can request that tutors reformat the timetable so that a 'free period' becomes a structured study session.

However if your DD doesn't really want to do A levels - perhaps she should look around for an apprenticeship instead?

She didn't particularly want to do anything tbh but they have to stay in education till they are 18. She is such a lazy sod with no ambition to do anything other than get a job doing as little as possible and move out. She is in for a shock!
Not even sure if they can apply for an apprenticeship till they are 18 either. She likes the subjects but seems to think she can coast along like she did with GCSE's. Maybe she will prove me wrong again.

To be honest it sounds like she shouldn't be there. Would a vocational course be better? Or an apprenticeship - yes of course they're available to 16-17 year olds! Or a job with either a training element or part time study?

If she likes the subjects I would wait a bit longer before panicking, some students are like this. In my first term at college I coasted along with little motivation and my Chemistry teacher told me that if I worked hard I'd achieve a C and he'd "eat his hat" if I achieved an A.

I achieved straight As, he didn't eat his hat. She may just be a slow-starter like me and many of my peers were. That's one possibility. The other possibility is that she aced the GCSEs simply because they were easy and they required little work (which they were) and she will go into college with the same attitude but be quite surprised when the exams don't go as well.

Either way like you said it's down to her to sort herself out.
