Strictly speaking, a double degree is a kind of academic qualification that is not recognized by the state, that is, there is no double degree in the state, but some universities offer two degrees to undergraduates. After graduation, they have two bachelor's degrees, but their education is still undergraduate.

The second bachelor's degree is one of the five qualifications stipulated by the state, ranking after undergraduate and before graduate. Full-time undergraduate students who have obtained a bachelor's degree will take the entrance examination for the second bachelor's degree after two years' work, and obtain the second bachelor's degree after two years' full-time study. Education is higher than undergraduate and lower than graduate.

Second, in short, if you get your second degree by taking the entrance examination for the second bachelor's degree, the words "second degree" will be marked on your diploma or degree certificate. If there is no specific explanation, you can ask the school that awarded the second degree to issue it. Of course, if you didn't get your second degree by taking the entrance examination for the second bachelor's degree, you still have an undergraduate degree.

I hope my answer can help you. Good luck!
