I’ve sometimes had ah in with higher but always had 1 or 2 periods with the advanced highers on their own which made a huge difference. It looks like this year I will have 1 pupil doing ah in with the higher class. I’m not massively sure how I will handle it, previously I’d get them on their own to cover the more difficult aspects then give them work to do during the higher periods, and leave them to do most of the reading on the less conceptually difficult stuff on their own. I don’t envy your position, I’ve only 1, that might go to 2, but if I get into a routine that works I will share whatever I can. I know that isn’t much in terms of advice, just some sympathy with your situation. You will get windows of opportunity when you get the highers on task, that’s all I can really suggest.
