See the table below for the re-examination results of students from Department 2 of 20 17 majoring in traffic information engineering and control. The most important thing to review is to refer to the postgraduate entrance examination outline for the first time, thoroughly understand the knowledge points in the textbook, and consolidate the knowledge points through practice for the second time. It is best to have internal exercises of Beihang University, such as final examination questions, and the exercises can also be combined with the first knowledge points. The last and most important step is to read the real questions thoroughly, at least three to five times, especially in recent years. If you have any questions, it is better for experienced seniors to answer them in time. 400+ seniors can help you. As long as you review well, the probability of being admitted is still very high. What we have to do now is to make up our minds and then concentrate on reviewing.
