Did I ruin my chances at Oxford
I'm an international student from the US, and I'm applying for Maths and Philosophy at Oxford after a gap year. I have a 1590 SAT, and I have a 5 in APUSH from junior year. I was also a John Locke Institute essay competition finalist. I'm was aware of the AP requirements for Oxford, so I took AP Lit, AP World History, and AP Government at school as well as self-studying for AP Chem and AP Calc. Personal circumstances meant I couldn't study enough for Chem and Calc besides almost the week before, so I think I got a poor score on them (3-4 range). I'm planning to retake them during my gap year alongside AP Physics C. I've also been averaging 7-7.5 on the TMUA, which I plan to take. Did I ruin my chances at Oxford, or do I still have a chance?
