Some science and engineering subjects require one, such as mechanical design and manufacturing, while others require two, such as food science and engineering, literature and history. However, last year, Shanghai Jiaotong University changed its business administration to number two, which is a precedent.

The math test is comprehensive, the math is high, the line generation and introduction are difficult.

Counting two is not an introduction, and the topic is easier than counting one.

Although the number three and number four exams are also very comprehensive, the difficulty of the questions is obviously reduced.
