So I am an American student looking at applying to Oxford for Philosophy, Politics, and Economics in the fall, and I have taken 3 APs, US Government and Politics, Chemistry, and Calculus BC.I didn't take more APs because my school stopped teaching to the AP system a while back, so we generally have to study a lot more for the APs than other students from other schools would. I took the SAT subject test Math 2 and got an 800 end of my sophomore year, and I am going to take the Chemistry and US History subject tests this June. I know they want at least 3 relevant APs and subject tests. Assuming I do well enough, are these enough relevant tests? Are there any other subject tests I should take that would be relevant? Also, I am considering taking the physics subject test in October. Would that help me at all, or would it either, one, not be relevant at all, or two, not get the the admissions team because of the deadline of October 15?
