I need to learn English seriously!

Hello italki people. I am studying in at an English medium university, yet, my level is pre intermediate. But, I have to have an advanced level of English in order to achieve success in my facultydepartment. I need someone to who can help me by talking in English . My native language is Turkish. If this person is interested in learning Turkish, I can also help for learning turkish as much as I can. To sum up, I am waiting for my new friends for to both have fun and learn a language. But, I want this person to be my teacher in addition to being a friend. I want her/him to correct my speaking mistakes in speaking, in writing even if these conversations conservations are informal and you can understand what I am saying. my says are understandable. I want to talk and write in English with as little mistakes as possible mistakes.

Thank youuu.
