The interview of a threesome is still very reliable, and the teachers are all within the system. The key is to be very serious and responsible. At present, teachers in many institutions are trying to cope with students' earning wages and telling them some routines to recite. It seems that it is ok. As a result, they didn't do well in the exam, so wasting money was a waste. Teachers of threesome pay more attention to the improvement of students' own answers and guide them to say their own words, with a high pass rate.
