Why are you paying £25k a year? I haven't budgeted for this !
My DC is doing GCSEs and has ADHD, they asked me to make sure they are awake so they don't miss any exams, and provide bountiful revision snacks as support.
I always ask how exams went (because I'm interested and it is a little fun), I know what exams are that day. I check there isn't anything practical they need - like equipment or a lift to an exam in torrential rain, and general welfare check they're not burning out. I'm fairly sure this is what my parents did too. No lifts or equipment has actually been wanted, but I feel like it's supportive to offer.
Fingers crossed I feel like the exam period has gone quite smoothly so far, neither of us has felt particularly stressed. I feel like I know what's going on and have been supportive in a general sense, but not involved in any actual revision.
A subject teacher contacted me earlier in the year about some specific coursework issues that I helped my DC resolve by discussing, and my DC asked for a tutor in one subject which I duly booked, paid for, and transported to.
Maybe I am overly involved? I vaguely feel as neither of us feel stressed - out it's been a kind of OK level of support. I definitely feel like they're going to 'own' the success (hopefully not lack of) themselves, all the actual work has been them and not me.
I do know some much much more involved parents, but I doubt my DC would want me doing that.
