Montgomery Blair Informatics Tournament 2021 Spring Round (Registration live!)

Competitors can join our Discord server here

The Montgomery Blair HS Computer Team is proud to present the fourth iteration of the semi-annual Montgomery Blair Informatics Tournament (mBIT), which will be held online from 10:00 AM — 2:00 PM EDT on Saturday, June 12 (6/12/21). If you are interested in competing, please register at The contest will be hosted on our personal servers at All problems were written by the Montgomery Blair Computer Team, including @tqian, @gabrielwu, @galencolin, @xams, and others.

mBIT is split into two divisions: Standard and Advanced. Teams may choose which division to compete in. Standard division problems are roughly USACO Bronze to Silver difficulty, while Advanced division problems range from USACO Silver to Platinum. Most Standard problems could be found on a Div 3 contest or early on in a Div 2 contest. Advanced problems are more comparable to Div 1 (and more difficult Div 2) problems.

mBIT allows teams of up to 4 competitors! Anybody may compete, regardless of their age or country. There will be Amazon gift cards reserved for the top high school teams in both divisions, in addition to the top overall teams in the Advanced division. To qualify for “high school status,” all members of your team must be current high school (or middle school) students.

Prizes (per person):

  • $50, $25, $25 for the first, second, and third HS teams in Advanced

  • $25, $10, $10 for the first, second, and third overall teams in Advanced that are not among the top three HS teams

  • $25, $10 for the first HS team and first MS team in Standard

  • All prize winners will get a Wolfram|Alpha Pro subscription, and the top middle school Standard team will receive AoPS coupons.
