Hello!
I am a native English speaker.
My lessons are conducted in a conversation format, so a basic understanding of the language is recommended. I also speak and understand Polish a little bit so I should be able to elaborate a point, there where necessary.
On a much personal note, I am varsity student myself and I have been an English tutor for over 6 years, so I have got a ton of experience.
So I welcome all of those who want to better their English, from the rudimental daily chit-chat to the more advanced technicalities like vocabulary learning, familiarizing one self with the scientific jargon and more.
My contact information can be found at the end of this thread. I can be reached via email or/and by phone.
