i mean , for example people who English is not their mother tongue can pass TOEFL (Test of English as a Foreign Language)or IELTS (International English Language Testing System )and for the people who are not Chinese and their mother tongue is not chinese language they should pass HSK (hanyu shuiping kaoshi) .... .
i want to learn Russian language , but i don't know what s the highest point , i mean is there any examination in Russian language like other language , is there any standard or not ?
