How to register your Russian progress

The best way is to use duome browser extensions available for Google Chrome, Mozilla Firefox and Microsoft Edge browsers.

Otherwise - make sure that Russian is currently selected on Duolingo and update your duome page as usual; if your score isn't updating - sometimes you need to "unlock" your score by doing at least one lesson in this language; also, sometimes Duolingo reports some other language pair regardless of your choice, this can be fixed by briefly switching to another language and back again (please, share your experience on the forum if your language score remains frozen).
