Physics Degree with Media Studies A-Level

I think you should fight back (get your parents involved) about not being able to change course. It's in the college's interest to facilitate studies of STEM subjects. It would require some catch-up but since these are A-levels we're talking about it's not infeasible. The good news is that in general studying Media Studies shouldn't be a problem as long as it accompanies two 'good' subjects. However, you might want to make what you mean by a 'good' university more clear. If somewhere like Bristol is what you're aiming for, their entry requirements are AAA and you'll probably want to demonstrate that in your AS year by getting solid As in mock exams or demonstrating that level of progress to your teachers. If you end up really getting into and excelling in Physics and Maths A level then I don't think this potential problem will rear its head. Where having Media Studies in your selection may be a problem is if your grades in Maths and Physics are at the lower end of the applicant pool and every decision is down to the wire. Media Studies will form part of your final offer so you'll still have to devote plenty of time to that subject. On that basis, and because I think Chemistry is a more interesting and useful subject, you should transfer if you can. If not, don't worry and focus on getting those As, particularly in Maths and Physics.

That being said, this is contingent on you not massively downgrading your mark. If you are aiming for an A/B in Media Studies and convert to aiming for a C/D in Chemistry that might be a disadvantage. And you will absolutely have to commit to catching up. Did you get as good a GCSE in Chemistry as you got in Maths and Physics?

Also, I'm just going by the impression I get from university admissions criteria, this might be different from what the departments actually think, which is hardly well communicated. If possible, I suggest contacting the admissions department of several universities and seeing what they have to say.

Thank you so much for your reply as it told me more about the system than the lady at the Student Services at my college as she just shouted at me that I had a lot of time to make up my decision. I am now getting my parents involved as they believe it is my life and the college should not limit my options like that If I am capable of getting a good grade. I am also very dedicated to getting As in all of my A levels as I really want to go to a good university and have basically caught up with 1/2 of all of the chemistry class has done within 1 weekend.

As for my GCSEs, I got Maths (A), Physics (A) and Chemistry (A) whereas I ended up with a B for my media studies. This alone should be a sign that I am more capable in chemistry rather than media and there should be no problem of changing. Also, I took media because I was always told I am very good with photoshop and it would be a nice break from the academic subjects however Media is not as easy as I thought as the exam aspect of it is rather difficult. I am currently getting A/B in Physics and a D/C in maths (really bad teacher, whole class has complained) and a A/B in Media however I believe I could turn this into As with some solid revision.

Once again thank you for your response as it cleared everything up for me quite a lot.
