@11prep per week 90 mins dancing, 3 hours music and 2+ hour sports, 1 hour for foreign language lessons. There are 8 hours available every day if you exclude school/sleeping time. I struggle to understand why other parents say this is too much a stretch.
Let me restate: 1-2 hours is from May only. It is total study time (including practice papers and atom learning mocks), if you took 11+ exam you know each paper required at least 20 mins per subject and you need to practice a lot to stand a chance no matter how bright the kids are...
And this is the average level of intensity or even lower end compared to other families I know of.
