Specialized courses vary from school to school.
It is of little significance to know the score line of postgraduate entrance examination.
For example, the score of 350 at Jiaotong University is totally different from that at Donghua University (I'm not sure if Donghua has this major, assuming it does).
Mainly because of the difficulty of specialized courses, some schools may adjust the scores of specialized courses according to the enrollment situation of the year, so as to maintain a stable score line for others to see.
If you have the strength, I suggest you try Jiaotong University in our school. If you can't get a high score (about 350 points), you can also consider adjusting the score of Jiaotong University, and enrollment will give priority to adjusting the score of the exam (Shanghai University seems to always do this, which has caused many people's dissatisfaction). If you want to be stable, you can go directly to college.
As for Huali and Donghua, are there any mechanical majors? I haven't heard of it. If there is, it should not be famous.
