Dude I started using the Lingoda thing a little time ago. It's legit and the promo code is legit too. It's like, you get 50$ off and the guy who posted the promo code gets 5 free classes. If you use the code FVHUKM you'll get a 50$ off and I'll get 5 free classes. When you register they'll provide you with a code which would work the same way. If you are planning to register for a new course in Lingoda, feel free to use the code FVHUKM since it's a win-win deal. I hope this helps.
