It's going terribly.
I have a 16 year old who knows that GCSEs are cancelled so doesn't see the point and a 15 year old with SEND who won't be doing exams.
I work (at home currently) in a very full on job so am on zoom from 8.30 till 4 most days without a break and then have to do work which results from this.
I start trying to wake them up at 8, end up having to start work with them still in bed at 9. They wake up about 1 and watch TV / play games till I finish work and then we start with 'homework'.
In the meantime I'm getting loads of emails from schools with 'flexible' tasks which is driving me to the point of breakdown. I spent a couple of weeks, stressed, feeling like a failure, the closest to depression that I've ever been. Not helped by the comparison with other families whose kids seem to do exactly what they're told all the time.
The way that I've dealt with it is to let it go. I cannot teach them alongside my job. I will do my best but I can't do anymore than I'm already doing.
The 16 year old has had 'the talk', if he decides to ignore it, he will deal with the fallout. The 15 year old is much more likely to benefit from life skills so he has jobs that he needs to do.
When the chaos created by this crisis abates I will take some annual leave and we will be able to find a way through but for now and for my sanity I just have to accept what I can do and let go of what I can't.
