I didn't realise she would need to make decisions about sixth form so early in the year. She is really torn on what subjects to do, although knows she definitely wants to stay on at her school. Maybe I will try to speak to her about it in the first couple of weeks.
If there is any chance she won't meet grade requirements then look at and apply to other places too. Plus if there are colleges that offer her choice of subjects apply to one anyway in case in 9 months she wants a change of scene. You can hold multiple offers right up until results day. (Read the posts from parents whose DC didn't have Plan Bs.) She doesn't need a final choice on subjects, when she applies, but if timetabling is done around choices she may find a later switch isn't possible (especially if she picks an unusual combination.)
So if mocks are in late November, do you think she would be expected to revise through Oct half term and we shouldn't go on holiday?
Personally I wouldn't with Nov mocks (others will disagree), but would look to go Feb half term instead perhaps?
Oh sorry, another question! Is it worth buying the revision books for each subject or are these largely replaced by websites now?
Personally I think lots of the revision guides are really good. It is all there in one easy booklet. You can put posts its in, it's an easy reference, Mum/Dad can test from it. As soon as you rely purely on websites you are relying on the young person not to get distracted onto other things.
