1, check the interview results of this major in previous years. This year's math is not much different from last year's, and the total score should be similar.

2. If the step 1 is clear and there is still a play, you'd better go to school in person and find the tutor you are looking for to find out. Telling the truth, my professional grades and math are not very good, which is very important for my tutor. If the mentor values it too much, you can only choose a mentor again. This step is crucial. If your tutor doesn't approve, it will be very difficult.

3. Before you go to see your tutor, you should make more efforts in professional courses, especially pay attention to the professional topics of Harbin Institute of Technology, so that your tutor can feel that you are very interested and have a certain professional foundation.

If step 1 doesn't work, contact and adjust quickly. When choosing a school and a tutor, it depends on whether the subject of the school has a future and whether you can learn something. Otherwise, two or three years of postgraduate study will have no practical effect.

Good luck!
