Hello Codeforces!↵

![ ](/predownloaded/e0/b6/e0b6aa48b6844684f79ff84fdcea7b8570e0d033.jpg)↵

I am pleased to invite you all to participate in [Codeforces Round 981 (Div. 3)](https://mirror.codeforces.com/contests/2033), which will start on [contest_time:2033].↵

The format of the event will be like any Div. 3 rounds:↵

- 6-8 tasks;↵

- ICPC rules with a penalty of 10 minutes for an incorrect submission;↵

- 12-hour phase of open hacks after the end of the round (hacks do not give additional points)↵

- after the end of the open hacking phase, all solutions will be tested on the updated set of tests, and the ratings recalculated↵

- by default, only "trusted" participants are shown in the results table.↵

I encourage participants with a rating of 1600+ not to create new accounts but to participate unofficially.↵

Only [trusted participants](https://mirror.codeforces.com/blog/entry/59228) of the third division will be included in the official standings table. This is a forced measure for combating unsporting behavior. To qualify as a _trusted participant_ of the third division, you must:↵

- take part in at least five rated rounds (and solve at least one problem in each of them),↵
- do not have a point of 1900 or higher in the rating.↵

Regardless of whether you are a trusted participant of the third division or not, if your rating is less than 1600 (or you are a newcomer/unrated), then the round will be rated for you.↵

Also, it will be a round with [unrated register](https://mirror.codeforces.com/blog/entry/133293). If you already registered as rated participant you can change registration type [here] (https://mirror.codeforces.com/contestRegistrants/2033).↵
