The contest will be 3 hours long and scored by the sum of points for problems solved (harder problems worth more points). There will be a wide range of problem difficulties, from Codeforces Div3 level to about Div1 B/C. Competitors in the second and third divisions will most likely find it interesting.
The problems have been prepared by students at my school: me (ekzhang), Vincent Huang (tastymath75025), Autumn Tan, Wuyou Xie, Sam Ziegelbein, and Timothy Qin. We would also like to thank Kevin Meng (mtr361) and Maxwell Jiang (rocketscience) for helping test the round.
Please visit this link to register for the contest. The round will be held on HackerRank (binary scoring will be used), and a live scoreboard will be available.
Good luck and and have fun!
