Hello artem!
I am a bilingual english speaker, and have acquired 8/9 bands in IELTS under british council, as i had to go to united states for studies, i have already completed my studies here and have been living in the states for 5 years now. I am excellent english speaker, writer, reader and listener. As i am myself bilingual, i do understand the struggles of a non- speaker, and can help with my own tricks, as i have also tutored for 1 year in india for IELTS, i have a tons of material for practice and am familiar with the questioning pattern. I'd be happy to help you.
Thanks,
Hir Pandya.
