DD is at a state school and no tutor. We are putting all our eggs in one basket with the Sutton Grammars, as we are local to Nonsuch and know it pretty well (and also a decent journey to Wallington).
DD is as able as her DB (who got into his first choice grammar no problem), but it doesn't feel like the school catered for that as much with her - perhaps because of lockdown, but it always felt a bit like that. So we started prep at home in February, relaxed, typically half an hour 3 times a week. But she also reads and writes stories in her leisure time anyway, and loves logic puzzles and codes, so a lot of the things she chooses to do is informal prep (but don't tell her that!)
A couple of things recently have made me worry about her ability to cope with pressure outside of her comfort zone, so that's what I'm most worried about with this process.
