Adds a custom standings tab to Codeforces & shows your country rank after completion of every contest This extension is designed for Codeforces users to easily view contest standings filtered by their educational institution. It adds a custom “College Standings” tab to the standings page of each contest, allowing users to see how participants from their organization are performing. This extension also provides a new feature to know your country rank in the standings page itself.
Carrot
Rating predictor for Codeforces For an active contest: Carrot calculates rating changes according the current standings when you open the ranklist, and displays them in a new column. Carrot also adds a column showing the delta required to rank up. The delta calculation is done in real time a̶n̶d̶ ̶i̶s̶ ̶1̶0̶0̶%̶ ̶a̶c̶c̶u̶r̶a̶t̶e̶ (see note below). For a finished contest: Carrot displays the final deltas of each contestant in a new column and shows their rank change, if any, in an adjacent column. For both active and finished contests, Carrot displays a column for performance, the rating at which the delta would be zero. Each of Carrot's columns can be toggled according to your preference, so as to not clutter the ranklist more than you would like. Carrot communicates only with the Codeforces API and runs entirely in the browser. Note: Since all required data is fetched and processed in the browser, Carrot is not ideal if you have a low data cap on your network. If so I recommend using CF-Predictor instead: https://codeforces.com/blog/entry/50411 Note: The rating calculation is no longer 100% accurate since the new rating system was introduced. See https://github.com/meooow25/carrot/pull/18 for details.
