I studied Russian at a local community college, with a native Russian teacher who was from Siberia. I took two courses (did homeworks, took exams, did speaking). The college refused to offer the next level course, even though many of us signed a petition And the professor was willing to teach it.
Around the same time I also attended parties at the Russian center here, and after the college courses ended, I took group lessons from a teacher who was from St. Petersburg (mostly 3-4 students including me, so we got a lot of individual attention). The organizer was from Moscow and she Helped us too. Having native Russians teaching really helped my Russian pronunciation but I really struggle with grammar - mainly the Six Cases. I never mastered them.
The parties went on for about 18 months. So I had a lot of exposure to the language and culture until the center closed two years ago. I have been out of touch since, except for the Russian songs Which I love and listen to frequently.
I was never good at conversing in Russian. I need the dictionary, which doesn’t work well if I am talking to someone.

I am more comfortable reading and writing.
There is a Russian meetup group here that practices speaking but I don’t attend it because of the pandemic. I am very surprised that they are meeting in person. So I try to brush up my Russian on my own, when I can, but I do much better in a classroom Setting. Some day I may join the meetup group but they have already advanced, so I may not feel comfortable There.
