I'm actually an English teacher, but my Russian and philosophy courses have been more popular among Bitcoiners, so here is one more class for Beginner Level Russian. Zap me 10000 sats for entry to the whole course (15.5 hours of lectures + lots of quizzes and extra resources). More information on my website, which is where the course is hosted:
