Format. The USAMO is an invitation-only proof-type examination administered to approximately 500 of the best and brightest students from the U.S. and Canada. Qualification is based on AMC 10, AMC 12, and AIME scores. No calculators are allowed on this two day, 9 hour exam (two 4.5 hour sessions).

How many people get Usmo?

Cutoffs, based on AMC 12 indices, are determined so that approximately 260-270 students qualify for the USAMO. Cutoffs, based on AMC 10 indices, are determined so that approximately 230-240 students qualify for the USAJMO.

Why the AMCs are trivial?

It is trivial to show that they will intersect exactly one side of the triangle (you may have to extend sides). A median is a cevian intersecting the opposite side at its midpoint. If all three medians are drawn, they concur at the centroid of the triangle.

What’s after Usamo?

The first in this series is the American Invitational Mathematics Exam (AIME), followed by the USA Mathematical Olympiad and Junior Mathematical Olympiad (USAMO and USAJMO). The top participants from the USA(J)MO are invited to the Mathematical Olympiad Program in the summer after the competition.

How many students go to Usamo?

250 students
Starting in 2011 and as of 2019, the IMO selection procedure is as follows. In the USA the main olympiad event is the USA(J)MO held in April each year. Roughly 250 students qualify for the USAMO and 250 students qualify for the USA(J)MO via scores on previous short-answer contests.

How do I know if I qualified for AIME?

Navigation. The AIME (American Invitational Mathematics Examination) is an intermediate examination between the AMC 10 or AMC 12 and the USAMO. All students who took the AMC 10 and had a score of 120 or more out of a possible 150, or were in the top 2.5\% also qualify for the AIME.

How hard is it to get into USAMO?

There is no farther than USAMO qualification to begin with. Only about 250 students qualify nationally. Around 20 join for camp and 6 represent USA in IMO after gruelling one year long training and numerous interim tests. With that said, USAMO is basically national level competition for high schoolers.

How will the AMC determine USO(J)Mo qualifying scores?

For this 2019-2020 competition cycle, the AMC will uphold this process to determine USO (J)MO qualifiers. Acknowledging that some students may have taken both AIME I and AOIME, both scores will be considered when setting cut-offs for those students. The AIME I and AOIME cutoff scores will be split.

What is a good AMC 12 score for USAMO?

But USAMO counts both your AIME and AMC scores, which means a bad AMC score isn’t very helpful. Your best bet is to get an AMC 12 score of around 120-130. For AIME, doing a lot of practice tests and reading solutions should be more than enough to prepare you for it.

How are USO(J)Mo indexes calculated?

The student’s USO (J)MO indexes are calculated as follows: There are many math competitions in the United States. Of those, only would take you to the IMO (International Math Olympiad), the highest level math competition for high school students in the world!
