Hi there,
Thanks for reaching out.
It sounds like you've picked a very good and complementary set of A-Level subjects which can set you up for a lot of science-based uni courses, not just medicine. You could do... Biochem, Biomedical sciences, Clinical sciences, Pharmacy, Biology, Pharmacology, Chemistry for drug discovery. And, if you wanted something a bit different... Chemical Engineering, Electronic engineering, Business/Management, Accounting and finance. All of these you would be eligible for at many unis with AAA grades 🙂
Open days are a good call, as are uni websites' course catalogues, the complete university guide for initial research into which unis are good for your chosen subject, and talking to student ambassadors online, for example via Unibuddy or The Ambassador Platform.
And did you know there are plenty of jobs you can do with any degree? ... Project management, marketing, copywriting, science writing/journalism, working with animals or children, working at a uni, for the intelligence services, in consultancy, in systems/process engineering, you could go into air traffic control, banking, teaching, do a PhD if you wanted, lecturing.
You don't have to have your whole life planned out yet - just focus on what you enjoy, go to a few open day course presentations and see what you think would suit you best.
Hoping this helps 🙂
