What for?
I've been studying English for...(it's even scary to reveal)...approximately 20 years)))) - since I was 7 or 8))
Nevertheless, my knowledge does not correspond to the YEARS I've devoted to it, probably because I studied at a post-soviet school (those who are from the ex-USSR countries may understand me:-)).
Mostly, I practised English at school and university. When I was a sophomore I took part in a popular programme amongst students, "Work & Travel", and travelled to the US - to polish up my English and gain some international experience. After I returned, I was completely in love with America. I practised the English language just a little bit at work.
At present, with my family, we are thinking of moving to an English speaking country, thus the level of my language skills is crucial. Hope to polish it up via italki!
