Generally there's not really a lot of actual choice...
Most schools will want English x 2, Maths, Double or Triple Science, a Humanity (so History or Geography) and then a MFL.
DD's school also has Infotech, Citizenship and RE as compulsory for Y9 and then pick one of RE or Citizenship for Y10.
So they only really get 2 free-choice options and at her school you have to take a visual or performing art (so Music, Drama, Art, Graphic, Photography, Textiles, Design Tech or Creative Media Production are on offer).
If you break it down that way, you may find it easier to see what she gets to choose from.
We went with a BTEC as one of DD's free choice options as there is no exam... it's all continuous assessment, so take a bit of pressure off in Y11.
