Tongji's machinery is quite strong and difficult to test. Be prepared for this.
There is no need to list public courses. Tongji is a specialized course of Mathematics-English-One (except Russian and Japanese), such as mechanical design, mechanical principle, material mechanics and so on, you must know. Find information about remedial classes or sign up yourself. I'm talking about the counseling materials for professional courses. You can buy it or ask yourself at school. The rest is to make a study plan according to the general routine plan and carry out boring study. Work hard and cheer up, and you will succeed. This is my opinion.
In addition, on the day when I decided to start the postgraduate entrance examination, I couldn't relax for a day, not for a day.
