<p>Long story short, I only have the ability to take Math IC or Math IIC. I'll be taking Math IIC since it's recognized more. Which subject should I study as the second one? I'm planning to take the subject tests in November this year, so tell me a subject which I can adequately prepare for and preferably score above 650 in it before November. I was thinking about doing Physics, since I'm studying Mechanics in Math, which has quite a few physics elements and I find it quite interesting. Other option is USH. I think I should have the general knowledge of it since US is my country of citizenship and not knowing about its history would kinda suck. But I can always catch up on that later.</p>
<p>Right now the question is which subject can I adequately self-study for before November? Also provide the recommended sources from where the knowledge of recommended subjects can be gained.</p>
<p>Thanks.</p>
