Well, this comes from someone who took both the general test and the subject test all in one day after a few hours of sleep. Sonoid2 might have taken both exams on the same day because that is how it is done now, but find out. Everyone in my honors class was aghast to hear that I had done a doubleheader because they had done the tests on different days. I was the consummate procrastinator.
If math is not your strong suit, then two months is not a lot of time to prepare.
Of course, I did not prepare for either one, beyond running through the free practice booklet on the subject test. But I was a math minor, so I suppose that helped me on the quantitative. On the other hand, I did not do particularly well on the analytical. If I had taken, say, a few hours to prepare, I would have done much better on that portion. I went in almost blind.
I think I took one of the last pencil-and-paper tests, and I was competing against other grads who were taking the computer test and getting, on average, something like a hundred points higher. I thought that was dreadfully unfair, but I was still accepted at half of the schools I applied to, including my top choice.
Research your schools. Some even require no GREs, but that might vary by discipline. Others don't care about non-relevant portions of the general test. As I recall, UCLA's English Department required a combined score of 1300--the language portion of the general test, plus the subject test; they didn't care about quantitative and analytical. And so on.
