The rating is a modification of Elo rating, several details can be read in a fuller form. According to the rating, the contestants are split into two divisions: the second one (the weaker one, amateurs) and the first one (the stronger one, pros).

1 month ago - 2 contests. At the same time, Div. 3 was created for users rated below 1600. There is also a Div. 4, which is for users rated below 1400. During the period of time when the user tourist (Gennady Korotkevich) had a rating of >4000, he was given the title "tourist"; likewise, during the time when the user jiangly (Lingyu Jiang) had a rating of >4000, he was given the title "jiangly". Codeforces was created by a group of competitive programmers from Saratov State University led by Mike Mirzayanov.

Now I don't like the idea to run in parallel Div. 3 and Div. 4 rounds (like we do for Div. 1 and Div. 2). Div. 3 rounds are harder to prepare and I don't think we can host them more than once per ~2 weeks. It means that such rounds will not give new contests for newcomers and grays/greens (I think Div.

This round will be combined for Division $$$1$$$ and Division $$$2$$$ and will be rated for everyone. You will have $$$2.5$$$ hours to solve $$$8$$$ problems. Between $$$6$$$ and $$$7$$$ problems will not be split into subtasks. Also, between $$$6$$$ and $$$7$$$ problems will not be interactive, so you are recommended to read the guide to interactive problems if you have not encountered them before. We would like to thank the following people for making the contest possible:

November 21, 2019 - Codeforces has two divisions, one for the pros called Division 1. Division 2 are for people who do not take part in competitions or the people with rating below 1900. Division 2 problems are easier to understand and solve than Division 1 problems.

For each test case, output a single line containing the correct division in the format "Division X", where $$$X$$$ is an integer between $$$1$$$ and $$$4$$$ representing the division for the corresponding rating.

It bears mentioning that the disciplines of computer science and software engineering are so vast, that it's quite possible to be a successful professional in your specialization while still being a Pupil on Codeforces. Contest skills which you may wish to develop include: algorithmic fundamentals, mathematical problem solving, and speed and precision of implementation. In my Pacific Northwest region, we prepare Division 2 contests (roughly equivalent to Division 3 on Codeforces) to provide a fun and educational experience for novices.

I've noticed "Codeforces Round #521 (Div. 3)" coming up, but cannot find any details about division 3 (only 1 & 2 appear to be mentioned in the help section of the site). Does anybody know the rating cut-off for these div3 contests?

2 rounds we don’t change the rating bound between divisions. So Div. 1 edition of the round continue to include participants with the rating from 1900 and above. As an experiment, we plan to host rounds of simplified complexity (Div. 3). In such rounds, the official results will include participants with ratings less than 1600. We plan to include in these rounds simple training problems that will help beginner participants to gain skills and to get new knowledge in a real contest.

To break ties, codeforces sums the number of minutes taken to solve each problem, plus 10 minutes per incorrect submission to an accepted problem, whoever has the least such number is ranked first. The scoreboards are available here: Division I and Division II. If you have any questions during ...
