Nitrogen guide education attaches great importance to the cultivation of students' mentality. I remember that on the first day of class in their home, the nitrogen guide teacher said that if I was in a bad mental state during the interview, it would leave a bad impression on the examiner and affect my passing. So the teacher takes us to practice desensitization training eight times a day. After studying for a period of time, my mentality has obviously improved. I am not only full of confidence, but also fluent in speaking.
