It has nothing to do with level 4 or anything.
Nankai didn't take double degrees from the beginning, and both of them were transferred from minor.
In other words, if you are a major and want to get a double degree in B major, you need to choose a minor major first. When you have enough minor time, you will switch to double major. If you have enough double major credits and pass the exam at the same time, congratulations on your double degree.
In the case of failure, if you have a double degree, but the double degree is not enough in the last class, but the minor class is enough, then there is no cost. The school will issue a minor certificate, but not a degree.
And if you fail in minor subjects, such as class hours and grades, it will not affect your original real major.
It should be noted that all majors can have double degrees. For example, Nankai Business School (except for graphic file major in business school) and School of Economics cannot double major. For example, if you are a marketing major in a business school, you can't choose a dual-degree major in business school and School of Economics, except for graphic files in business school, but you can still choose graphic files. (But this major is dead. )
In addition, Tianda and Nanta have a joint major, which seems to be a photoelectric major (I can't remember clearly, but I can find it online). This major was in Nankai two years ago and in Tianda two years later, and obtained diplomas from two schools. Yeah, but this major is very difficult, and you often hear complaints.
There are also professional achievements and so on. If too many people register, they will need to brush off those with low credit scores.
In addition, if you want to minor (that is, double major) in certain majors, there will be exams.
For example, there will be interview exams for language majors and written exams for mathematics majors. If you fail the exam, you will fail. Popular majors (difficult majors) will be like this.
