Thing is, as a "on principle" question of course she should decide what subjects to study and where to study them. However.
She is a bright girl, predicted As and A*s for GCSEs (in Wales so still letter grades). However, she does no revision, no homework and her attendance is very poor. She hates her secondary school, and will think of every reason to not go in. She struggles socially (being assessed for Autism) and with low mood. After school she dances, sings and does drama - which she is very committed to. She probably spends around 16 hours in an average week at class. Most weeks there is something extra, so she does more.
She insists that she is going to stay at her secondary school and do A levels. I can't understand it, as she has been so unhappy there. To start with she was going to do A levels in Drama, Dance and Music - with English lit at her 4th for the first year. I asked her to look at a couple of other colleges - she looked at one with a very highly regarded Performing Arts course, but decided that she didn't want to spend all day doing Musical Theatre and then come home to do all her dance lessons. We left it at that.
Only now her school have said there is not enough interest to run either the dance or music A level courses. She is determined that, despite this, she is still staying there. Her latest plan is to do Drama, Literature,Physics and Welsh. Which is random, as previously she said she hated learning Welsh and hated science. She wants to be a stage or film director, with dance teacher as her backup career choice.
I can just see it going very badly if she is going to a school in which she is very unhappy and doing subjects in which she has no interest, just because (I think) she doesn't much like change.
AIBU to put my foot down and say "Actually you don't have free choice - you are still a child and you get to choose from the options I agree with - and this is not one of them."? Or should I just let her make her own mistakes?
