Should I bother applying for maths in Oxford? (Edit:I'll be applying for physics)

Go for it. If you perform very strongly on the MAT, your chances are certainly non-trivial, though I'm not sure if any more can be said. Maths in general has a pretty high offer rate elsewhere and unless your other options are like Durham, St. Andrews, Imperial, or etc. (the main ones I can think of that reject a substantial number of applicants) there's a pretty reasonable chance you will get most of your offers. Unless Warwick has changed its admissions policy in the last year, you would likely get an offer from them as well. Below this have a think about UCL, Edinburgh, Bristol, Bath, Lancaster, Birmingham and the like just to name a few good ones.

I recently got my predicted scores back (A star in maths and chemistry, A in FM and physics), and the entry requirements require an a star in FM (which I don't have). If I decide not to, I'll apply for physics there instead. Has anyone here got similar scores and had an offer? I know I can get A stars in the final exams (enough to get more than the entry requirements), but I don't know if I should risk it. I am also doing a maths book for my EPQ.

Thanks, I was considering Bath and Edinburgh. So they will likely provide me an offer?

yes you should get an offer from at least a few (realistically most) of the unis you apply to unless there is something wrong with your reference. St. Andrews, Imperial, Oxbridge or maybe Durham (my memory is failing here a bit) on the other hand all seem to reject a substantial number of applicants. St. Andrews has seemingly rejected a lot of people who have got into Oxbridge. Put down an AAA or AAB option as well. Lancaster is pretty good at this pricepoint and often accepts people in clearing with considerably less than that.

however I would try to push for an A* in FM like the other poster said (I don't think they're correct in their assessment otherwise though), because this would take out this worry completely.

@RichE is quite senior at Oxford and might be able to give better advice on whether it's possible to get an Oxford interview with an A in FM. (I would imagine so if your MAT score is strong but I am not really sure)

It's a bit early to give you final predictions - is there no movement on this if you improve in the next three months?

These are (what I gauge) will be the final predictions

Really silly - you could improve considerably over the summer. Talk to your teachers - I'm quite shocked tbh.

you mentioned that oxbridge reject a substantial number of applicants. unless OP is in the top 5 or 10% on the MAT, why wouldn't they reject OP if OP does not have the entry requirements?

Cambridge gives out interviews to people with A*AA predictions but deselects far fewer candidates before interview. I would just be guessing if I said anything stronger, I just doubt it's an immediate reject.
