New USA(J)MO Awards Announced!
Starting with the 2022 competition, we will be changing the awards for the USAMO and USAJMO. For the USAMO, the AMC will award Gold medals to at least approximately 6% of participants, Silver medals to at least approximately 12% of participants, and Bronze medals to at least approximately 18% of participants. For the USAJMO, we will continue to recognize winners but will increase the recognition to at least 20% of participants. For both the USAMO and USAJMO, an Honorable Mention will be awarded for each additional participant who scores 14 points or higher. Each year, the student selection committee will determine the exact percentages and number of awards.
Information Overview
Students who perform well on the AMC 10/12 are invited to continue in the AMC series of exams, ultimately leading to the International Mathematical Olympiad (IMO). The first in this series is the American Invitational Mathematics Examination (AIME), followed by the United States of America Mathematical Olympiad and Junior Mathematical Olympiad (USAMO and USAJMO). Top performers on the USA(J)MO are invited to participate in the Mathematical Olympiad Program during the summer following the competition. Participants from the Mathematical Olympiad Program are then eligible to be selected for the six-person team representing the United States at the IMO the following summer.

AIME and USA(J)MO Frequently Asked Questions
American Invitational Mathematics Examination
The American Invitational Mathematics Examination (AIME) is a challenging competition for those who perform well on the AMC 10 and/or AMC 12. The AIME has 15 questions, is 3 hours long, and each answer is an integer between 0 and 999. The questions on the AIME are significantly more difficult than those on the AMC 10 and AMC 12. The highest-scoring participants on the AIME are invited to participate in the USAMO or USAJMO. AIME Dates:

2. The AIME II exam time is February 12th. The AIME II exam, which was originally a bilingual Chinese and English paper, may be adjusted to a purely English paper.
AIME Management Resources:
AIME II Registration Form: Students eligible to participate in AIME will be automatically registered for AIME I.
AIME Location Change Form: Students eligible to participate in AIME must take AIME I or AIME II at the institution where they took the AMC 10/12. If the student's eligible institution cannot host AIME I or AIME II, the student may only take AIME I or AIME II at a different location. In this case, the competition manager at that institution must complete and submit this form.
United States Mathematical Olympiad and Junior Mathematical Olympiad
The United States Mathematical Olympiad (USAMO) and the United States Junior Mathematical Olympiad (USAJMO) are two-day, 9-hour, six-question essay/proof exams. The highest-scoring AMC 12 participants (based on a combination of AMC 12 and AIME scores) are invited to participate in the USAMO. The highest-scoring AMC 10 participants (based on a combination of AMC 10 and AIME scores) are invited to participate in the USAJMO. US citizens and students studying in the US and Canada (with qualifying scores) are eligible to participate in the USAMO and USAJMO.
The MAA AMC promotes inclusivity in our programs and competitions. We strive to create a mathematical community that empowers students of all genders, and each year we invite the highest-scoring female AMC students to participate in our USA(J)MO. These students are placed on an ambitious path that may qualify them for MOP, EGMO, and ultimately the IMO.

AIME and USAMO/USAJMO Frequently Asked Questions
Q. How do I qualify for the AIME?
A. The qualification parameters for the AIME vary depending on the results of the AMC 10/12 competitions. For the AMC 10, at least the top 2.5% of all scorers will be invited. For the AMC 12, at least the top 5% of all scorers will be invited. The exact results will depend on the difficulty of each competition.
Q. How do I qualify for the USA(J)MO?
A. The qualification parameters for the USA(J)MO vary depending on the results of the AMC 10/12 competitions and the AIME competition.
USAMO qualification will be based on the USAMO index, which is calculated as follows:
USAMO Index = AMC 12 Score + 20 x AIME Score
USAJMO Index = AMC 10 Score + 20 x AIME Score
Q. Who can proctor the AIME or USA(J)MO?
A. Students will be supervised by a teacher (preferably a math teacher) or administrator from their school; a math teacher from a college or university, or a responsible adult such as a math club coach or librarian, may proctor in person or remotely, at the teacher's discretion. Remote proctoring requires the teacher to monitor the student via video conferencing software. The proctor should not be related to any of the participants.
Q. When will I see my AIME results? When will I see my USA(J)MO results?
A. AIME results reports will be submitted to schools after we receive all AIME I and AIME II answer sheets, score all answer sheets, and determine the USA(J)MO selection index. Therefore, you can expect to receive your AIME results approximately 3 to 4 weeks after the AIME date.
USAMO grading takes place approximately 10 days after the test, and results will be posted on the website shortly thereafter. Approximately 2-3 weeks after the USAMO and USAJMO, we will email copies of the USAMO, USAMO solutions, USAJMO, and USAJMO solutions along with your total score to your test manager. We do not report scores for individual problems, only the total score. Please note that the AMC will not return your USA(J)MO papers to you.
Q. If you take both the A-date and B-date AMC exams, but one score is higher than the other, do you get to choose which score is used with your AIME score for USA(J)MO qualification?
A. We use the higher score. We match the two AMC scores with the AIME score, assuming we are able to find both AMC scores. This means the student spells his/her name the same way on all exams and took both AMC exams at the same school. If one or both of these important criteria are not met, we need to be notified promptly so that we can match the results. The AIME certification form is filled out by the AIME competition administrator and there is a section for students who qualified at multiple testing locations. Please provide this important information to the AIME competition administrator so that we can use this important information.
Q. What should I do if I need to take the AIME at a location other than where I took the AMC 10/12?
A. Students should take the AIME at the same testing location where they took the AMC 10/12 whenever possible. This is to ensure that the student's AMC 10/12 score can be accurately matched with their AIME score for USA(J)MO qualification. If a student cannot take the AIME at the same location, they will need to make arrangements with a different competition manager who has the proctoring materials and fill out a "Location Change" form. Our customer service office cannot assist in finding a new testing location; instead, students should use the other testing locations page as a resource to contact schools near them. Once the location is arranged, please email amcinfo@maa.org to inform our office that you will be taking the AIME at this new location instead of your qualifying location.
Q. What do I need to do if I qualified for both the 12A at my own high school and the 10B at another high school, but I want to use my 10B score for the AIME I take at my own school?
A. If you are taking the AIME at the school you attend daily, based on your AMC 12A taken at that school, it is important that the certification form filled out by your AIME administrator includes your name and the name and CEEB of the other school where you took the AMC 10B. Please ensure that the competition manager at the other school where you qualified knows that you will not be taking the AIME at that school, and that your own school's competition manager is aware of your intentions. We only use the AMC 10/12 scores as an initial check of your identity. For all other purposes, we rely on our internal record-keeping.
