I'm a student from Poland on Erasmus exchange studying at Strathclyde University, I can teach you formal and informal language used in schools and between your peers in any way you want, at home, in the pub etc etc etc
I used to give the private lessons with good results since high school to some people in various age. Generally I taught maths and physics what was directly linked with the field of my studies, but teaching is always teaching ;)
