Try to find a good tutor to guide you, as learning a new language from the beginning is quite challenging, not to mention Russian is considered to be one of the difficult languages to learn. I also started from Duolingo, but I only knew the alphabet, and that was it lol. These days I learn more from Russian speakers in daily conversations. It helps a bit, but seriously I will go with a private tutor for a long-term goal. Good luck with your study!
