Is the expression of IELTS speaking examiner a hint? ?

During the IELTS speaking test, some people will meet the examiner with a gentle smile and even say "Yes?" Finally. Answer? Does it look nice? I think I should speak IELTS well, and the result is terrible. A candidate met a very serious examiner, who didn't laugh during the whole exam and kept interrupting his answer. They should have done badly in the exam, but in fact their scores reached expectations. ?

Therefore, the expressions of IELTS speaking examiners can't imply your grades, so don't be misled by their expressions and words. Just play normally in the examination room with a normal heart.
