First Round Results

Again thanks to everyone who participated in the First Round of the 2017 USAAAO this year! We had a really competitive group this year, with an average of 15.5 and standard deviation of 5. Based the scores, the exam, and the number of participants we’ve chosen a cutoff score of 20. You should’ve received an email with your score as well as whether or not you qualified for the NAO. If you didn’t, send us an email at

We’ll try to have the solutions up ASAP.

Here’s a histogram of the results:

First Round Closed

The First Round of the 2017 USAAAO has now closed. Thanks to everyone who participated! We had over 200 participants from all over the country (and world), and we hope you all enjoyed the exam. Results and solutions will be posted shortly, so stay tuned. We’ll also be sending out invitations for the NAO, which will take place in just 2 weeks! Remember that the NAO must be proctored, so please reach out to teachers early if you think you might qualify!
