Hello Codeforces,

We at Programming and Algorithms Group, IIT Roorkee conduct Open Contest Series every year. It will consist of topicwise contests, interspersed with contests with mixed topics. These are aimed at people who want to strengthen their basic concepts via regular practice.

The problems used in the contests will be past codeforces problems, and the level of contests will be close to a Div. 3 contest. The duration of contests will vary from 2 to 3 hours.

We welcome you all to join the contests if you believe they can be helpful for you.

Join the group here.

The first contest will be held at 21:00 IST, 13th December 2021. Further schedule will be updated in the group blog as well as in this blog.
