Waves eagerly to Gelo (love that name, btw), Betel, and Yellowtip. Thanks to all. I'm just as terrified as you all were. I probably know all too well how it can go wrong. :(
Yes, Betel, we hired him someone to take him a bit beyond the A-level stuff to prep for the PAT. Quite a mini-industry hereabouts, and it's good for the penniless graduates as well. He's thoroughly enjoyed his sessions; for a while the FE college laid on some u/g sessions with an engineering guy at Wadham, too. Your ds is amazing, Betel; I've always thought so.
Yellow, thing is he can be as pigheaded as a MULE and as silly as a two-cent watch, but perhaps that's his mum talking.., or, as I hope, him talking to his mum.
I think tbh that either Ox or Harvard would do him, to address your question; it's a comfort that he has offers from Durham and Lancaster, and spent a really nice day there - Lancs, that is - last week. He's not a school snob at all, as his choice of the FE college shows, and he was quite taken with Lancaster, who also offer some money... :)
Lovely to hear your dcs are helping, Gelo and Yellow. If you message me, I might disclose his college choice, though of course that might change with reallocation and whatnot.
