@SunblockSue we are in a similar boat. DD is doing Biology, Chemistry, Maths, and Further Maths. She was invited to take the fast track Maths course because she got an 8 in GCSE Maths (a couple of marks off a 9) and an A in her FSMQ OCR Add Maths exam. The Add Maths course curriculum overlaps with A-level Maths, to some extent, and that is supposed to help.
So she will be studying the A-level Maths curriculum in year 12 and sit the exams at the end of year 12. FM is over 2 years, normal pace, exams year 13. The good thing is that there are only 7 students in her fast track Maths and 15 in the Further Maths one.
The main problem though - she was told she couldn't drop FM in year 13, if she wanted to - this is due to the school funding rules, they need to study 3 subjects in year 13. Also, many unis base their offers on 3 A-levels sat at the end of year 13 in the same session, so it's a bit useless to sit the Maths exam early. And TBH she doesn't need a 4th A-level, 3 of them would be perfectly fine.
So I'm a bit worried about workload in both year 12 and year 13. DD doesn't want to drop FM, as she likes Maths. However, I'm not sure whether she realises how tough the workload will be. She is considering either Medicine (:sigh) or biotech/biomed research for post 18. Not 100% decided yet.
Her days are quite full: 4 A-levels (with Maths being on a fast track). For her enrichment she chose Gold DofE, which means athletics training 2x/week (this isn't new, it's her usual sport), 12+ months volunteering in NHS 1x week, and likely an online 6-month cookery class (1x week). For DofE Gold, there will also be a 4-day expedition at some point and a 5-day residential trip.
On top of this, if she does decide to try for Medicine she will need to do UCAT prep, interview prep & wider reading, summer medical work experience, etc. I just feel like it's too much. Summer of 2025 will be crazy.
Having said that, DD is motivated and less sceptical than I am. She talked to her teachers and form tutor about the workload and she is confident she can do it. She also said something that sounded so mature so I kinda' stepped back and I'm letting her do her thing: "Mum, the workload for at uni for someone studying to be a doctor will be tough. If I can't cope with 4 A-levels and some extracurricular stuff, then I should probably do something else with my life".
