Be polite. A good attitude will leave a good impression on the examiner.
In the process of the exam, we must pay attention to the trial time.
Novel and interesting classroom introduction is half the battle.
In addition, the examiner must remember to clean the blackboard after signaling "candidates can leave"!
The exam questions are: listening and speaking, reading, writing, vocabulary, grammar and pronunciation. So students must not study with luck, or they will not act with you.
