I only did 4 ASs and 3 A2s, and got rejected from Trinity for physics and philosophy. Phys+phil is supposed to be a pretty intensive course, so I imagine the pretty minor workload of 4/3 subjects wouldn't really be considered enough. If I took a gap year and reapplied, doing double maths during the gap year, do you think they'd look on them more favourably?
Also (a bit off the subject), is double maths really necessary for physics? Most people I know who do physics at Oxford are doing further maths, but I feel it would look quite poor if I had a whole year off (even with work experience) and only did 3 more modules. Also, do you think they'd make me a conditional offer based on my double maths result?
