What course do you recommend I could apply to study for at university?

I really have no clue at this stage what I want to study at university. Ideally, I wanted to do medicine but due to not getting A* in GCSE biology and also not getting good marks in tests for AS level biology, I am currently rethinking what I want to do.

I got 7 A*'s (inc. English language, mathematics, physics and chemistry), 3 A's and 1 B in my GCSE's. In addition, I achieved an A grade in FSMQ mathematics.

I regularly do maths challenges, both individual and team. I've got Best in School etc. before, but I haven't received a Gold till now which I could've got this year because I forgot to turn up for the test and I did it at a later date and found I would've got a Gold and qualified for kangaroo. The thing is though, i've been doing the Senior Maths Challenge since Yr. 10 (in which I got a bronze). Aside from this, I love solving Rubik's cubes and have attended competitions. Also, i've got a Grade 5 Merit in guitar. Years ago, I used to do Kung Fu and got up till Green Belt.

When it comes to work experience, i've really only done volunteering at a blind centre and a care home for old people. I've even attended a mini medical school at Birmingham university. In the past, i've done charity work too.

That's about it. I really have no particular interests. I don't mean to boast but I find I have been one of the best mathematicians in my year at my old school and I think I am at this school, although I don't do further maths because I did C1 and C2 units in year 11. Aside from this, I am amongst the top of the cohort in physics and chemistry too but when it comes to biology I am just about average, which is why i'm thinking of reconsdering medicine because I don't know how i'll cope if i'm finding it hard to cope with AS level biology.

Preferably, i'd really like to do a top tier course because I don't want to let down my parents and brother who have always worked so hard for me and invested so much in me. I don't mean to offend anyone but after all this hard work from my family I don't want to end up doing something like biomedical science ...

Before, I forget my A-level choices are maths, physics, chem and bio but i'm planning on dropping biology and doing MAYBE further maths if I don't do well in the mocks

Thank you for reading this and any suggestions are greatly appreciated.

It sounds like you are quite interested in maths and the sciences, have you maybe thought about a natural sciences?

Here is a link to the Cambridge Natural Science degree to just give you a bit of an idea of what you can study: http://www.undergraduate.study.cam.ac.uk/courses/natural-sciences

Lots of other universities offer this course.
