Mainly tests to determine the level of English offered language schools, so do not be afraid, if you before the free testing will be asked to enter a name and specify your email address – a little later you are likely to be offered to this school by sending a letter to the specified address.
Any test will require you attention and 30-90 minutes of free time. To accurately determine your level, you shouldn't use any guides – you do it for yourself. Because all tests are different, to obtain a more objective picture, walk two or three tests on different resources.
Use any of the tests that you will like – they will help to determine your level of English: www.examenglish.com/leveltest, www.bkc.ru/try_test, www.english.language.ru/tests/virtualtest, www.reward.ru/placement.
If you prefer verbal communication, contact school of foreign languages, where for a fee you propose to pass the test.
