Hello Yevheniia! I'm a native speaker of English from California. If you would like to practice English, we have a conversation group that meets twice a week on Skype, at 1500 Kyiv time on Tuesdays and Thursdays. It is a very small group, and we focus on pronunciation and idioms.
Please let me know if you're interested and I can send you a link.
See you soon! / Val
