| No, it's not too late, but you can't just jump into USAMO. There are two ways of qualifying. You can take the AMC in February/March and if you get at least a certain number of points, you can take the AIME, which is held during the month after the AMC. Then they combine your AMC score and AIME score and if you're in the top 500 students nationwide, then you get to take the USAMO shortly after the AIME. The second way of qualifying is to do the American Math Talent Search, which has a bunch of proofs that you do at home (the AMC is a timed multiple choice test at your school). If you get some score, you get to take the AIME. You can only take the AMC if a teacher at your school organizes it. |
