The most important thing in proctoring is to understand that the proctor is not trying to fail the participant, but only to help to write an exam or Olympiad. Many people worry during proctoring and think that they can’t even breathe normally, but this is not so. You should be comfortable writing a proctored test, but don't go overboard. You shouldn’t sing or say the terms of the assignments out loud, just imagine that you are in a classroom with other students who, like you, are writing this test and do not really want to be distracted.
