The opportunity of a profitable business trip to Australia was turned up, and the decision had to be taken very quickly, and I do not have good command of English.
I called my friends, they advised SMAPSE - they are engaged in the selection of language courses. We found an interesting option - Embassy Surfers Paradise. Studyign is at a very good level, but at the same time you get very exhausted: the courses are very intensive but effective as after 2 months, things went, and I could normally take English speech by ear (write and read - even earlier). A little expensive, but it was worth it.
