How to choose A-levels (both subjects and school vs 6form )

[LittleOwl]

Hi
My DC is 15, GCSE in 2024, his school goes up to A-levels, from what I can tell respectable results. We have been living in the UK just shy of 2 decades and I find the whole A level choices point utterly bewildering.
is there any general guidance on what subjects for which Uni courses? Or is it really that you need to check all unis separately?
(DC has no idea what he wants to do in later life, looks like he is enjoying Maths, Physics, Chemistry)
What are the reasons to join 6 form college if you are happy at a school that goes all the way through? And we would have to start the process in autumn to look around?

thank you for pointers as I am starting to get worried

I know what STEM means. It doesn"t matter whether they are degree level. We're talking about Key stage 5 choices here and I was responding to your point that not everybody is good at STEM.

The OP was talking about A levels and university courses. That’s what I was referring to. Choosing the right combination of A levels for further study at degree level. No one was looking at shortage areas of employment which don’t need a degree were they? Although some do but construction workers, for example, typically don’t.

Yes that's what I am saying. If your ds wants to continue with Physics, Chemistry and Maths A level, that's a fairly standard combination that should be possible at all sixth forms. There may be some that don't offer Further Maths though.
For Science A levels there may be different entry grades needed if you take 3 separate sciences at GCSE and if you take Combined Sciences. Some sixth forms may require grade 7s and others grade 8s for example. Grade 6 only possible if extenuating circumstances.
For A level courses most sixth forms require a grade 5 in both Maths (unlikely to be an issue if your ds is considering A level) and English language.
