Flight control and navigation are the strongest, but the employment field is relatively narrow compared with testing. Testing is the hottest in automation every year. But then again, the employment of flight control is still very wide. In the teacher's words, even airplanes can be controlled, let alone cars and the like.

The best flight control instructors, such as Mr. Zhang Ren and Mr. Chen Zongji, don't take the postgraduate entrance examination every year, so postgraduate entrance examination is enough.

Miss Yuan is the best, but Miss Yu Jinsong is the most popular every year.
