Is it possible for me to do a physics degree

Bath cleary state:"Any subject may be offered for the third A Level." So I highly doubt you'll be at a disadvantage.

Unless enough of the other applicants have a decent FM grade

Well if that's what the Baths website states I doubt he'll be disadvantaged. So someone with an A in Media and someone with an A in FM should both be equal.

So after starting my AS levels, I found that I really enjoy Physics. The subjects I take are as follows:
- A-level Maths (C1, C2, C3, C4, M1, D1)
- A-level Physics
- A-level Media Studies
- A-level Polish (I'm a native speaker)

After the first month of A level I found that media studies was not for me as I found it meaningless and a waste of time. I tried to drop it however I was not successful as my college did not let me switch to chemistry. Now I regret taking media however I believe I could do well in it as I am predicted an A. My predicted grades are all As and I was wondering if it is possible for me to get into a college to do a physics degree at a descent university such as Bath or Manchester. I looked at the entry requirements for both and they seem achievable however i feel like I am at a significant disadvantage due to my media which is frowned upon. I was wondering if it is possible for me to get into these universities or if it is just a waste of time and UCAS application.

I think top unis would prefer FM - can you take AS Further Maths next year? Many unis may not count Polish at all.

If bath and manchester are the sort of level op are applying for there is no real need to take further maths admission wise (though it would help for first year maths modules) as physics isnt a particularly popular subject anyway

As someone that works with students on UCAS applications, I disagree. He will be a much stronger applicant with AS Further Maths and M2 would be a better choice of applied Maths module than D1.

The Polish will not count towards the offer from what it says on the Bath website.

He will only be a much stronger applicant if he can handle the extra pressure of AS further maths on top of his A2 subjects, and do well in it, if he was to do poorly or average in it, it would be detrimental not beneficial. imo this extra pressure isnt worth it because of where the op will be applying

If someone can't handle AS Further during their A2 year they shouldn't be applying for Physics at a top 10 UK University.

You'd be surprised how average at Maths a lot of people doing Physics at top 10 universities are. If you can handle A level Maths alone you should be able to manage it, although you might struggle with more advanced quantum mechanics modules.

As for AS Further Maths, its value really depends on what the content of the modules is. Mechanics modules are very useful. Knowing about matrices would be helpful. Learning about differential equations would also be useful. All these topics are covered in the first year maths modules at university, but learning the concepts beforehand can help. If OP thinks he can manage it I think he should try it. Nonetheless, with his current choice of A levels he's definitely qualified.
