I am a student in Shanghai. The professional scores of Ningnuo 2+2 and 4+0 are quite different. Do you want to ask if there is a big difference between the two? Is it difficult to change majors?

Only engineering has 2+2.

International economy and trade belong to the School of Economics, with only 4+0 and no 2+2.

Business is only 4+0.

It seems quite easy to change from 4+0 to 2+2 in engineering. 2+2 to 4+0 is more difficult.

However, even if it is not 2+2, it can still be exchanged. Anglo-American law can go for a year or half a year.
