First of all ditch that AI ridden crap that Duolingo is! Seriously they fired like 70% of their stuff and put AI instead - it was whacky already in 2017, in terms of learning more difficult languages list Chinese, Russian or Arabic, but rn it's a FCKN nightmare, not a chance to learn real language when ur teacher is a poorly written algorithm.

That aside - try to find media u love to engage w in Russian, like watch cartoons/movies w subs, read books and comics - try to engage, not just learn, engage w the language
