This might be slightly off-topic :) 
 
Just while browsing learning tools I found a site https://tools.veryuseful.website/ 
 
They’ve collected: 
- online libraries (like "Українська Література"), 
- free courses via Prometheus, 
- Duolingo for learning Ukrainian, 
- information about schools and universities. 
 
Useful for both students and adults. 
 
Also found [url=https://tools.veryuseful.website/] an awesome Ukrainian learning platform[/url] — maybe worth checking! 
 
Any other cool learning sites to recommend?
