Individual Round
Individual Round
The individual round contains problems on Algebra, Number Theory, Geometry, Combinatorics, and Computer Science. This round will be 60 minutes.
Relay Round
Relay Round
Teams will work to solve 4 sets of problems where for each set, each team member works on one problem of the set and passes their answer to the next team member, who will use that answer to solve their own problem, like a relay! No communication between team members is allowed, and you will only have the previous person's answer slip and your own question to work with. You don't have to wait for the person before you to finish before you start working on your problem. Each of the 4 sets is 10 minutes, but there will be a small time bonus granted to teams who submit their final answer slip before the 6 minute mark.
Guts Round
Guts Round
Teams will work together to solve 7 sets of problems. After completing one set, a team member will need to run and submit their papers up front and retrieve the next set. Teams cannot return to edit answers from a previous set. Scores will be calculated and posted in real time so that teams can gauge their standing. This round will be 75 minutes.
