Hi there, I got my offer for physics at Magdalen about a week ago. I got all grade 9s in my GCSEs, but your GCSEs look really good.
The way oxford decide who to give offers to primarily depends on your contextualised GCSE results (i.e. how well you did compared to the average at similar schools and with regards to your area), your PAT score (although I'm sure they're changing to ESAT going forwards so defos check the website), and then your interview results if you get shortlisted for interview.
My advice for applying would be to practice for the admissions test as, from what I've been told when I've spoken to members of the oxford physics department on residentials and open days, they care the most about your admissions test results rather than your personal statement. If you go on to get interviews tho, they're arguably more important than your admissions test, but you need to well in the admissions test to get interviews so yk, prioritise the test.
Obviously don't neglect your personal statement, but (in my opinion) too much emphasis is put on it.
Also like someone else said, do COMPOS. Entry for the main program closed a few weeks ago but defos get on the follow-along program if you can, it's really useful to show that you're interested in higher level maths and physics.
Also, reading some popular science books on physics might be useful so that you better understand what you'll be learning about with a physics degree, and better understand the history of physics; I've personally found reading books to be useful. As for suggestions, anything by Feynman is great e.g. QED, six easy pieces, six not so easy pieces. I found Chad Orzel's "How to teach quantum physics to your dog" and Manjit Kumar's "Quantum" to both be good introductory texts to quantum physics. I really liked Kip Thorne's "Black Holes and time warps" as well. "Chaos" by James Gleick was an interesting introduction to chaos theory, and Brian Greene's "Elegant universe" was a good introduction to string theory. Those are a few of the ones I read and enjoyed
All the best in your application, if you have any questions I can answer about the admissions process then I'll try to respond. All the best, and good luck
