DD is in year 12 taking maths, physics and chemistry and working at A*/A standard in all three. She was dissuaded from taking further maths despite an A at GCSE for reasons we've never fully grasped but went along with as it wasn't essential for her future plans.
She's really enjoying her maths course and is now leaning towards taking it at degree level but of course the lack of further maths would then be a problem. School have indicated that it's too late in the day for her to add it to her timetable without huge upheaval. Is it totally unrealistic to think she could self study the syllabus (obviously with our help and support) and sit the A level as an external candidate? She'd clearly have some catching up to do but are we silly to even be thinking about it?
