1. First of all, from the difficulty of the exam, this major is relatively simple compared with other science and engineering majors. But your math and English are poor, so this is more difficult, because there are still many subjects involved in this major, such as engineering mechanics, engineering structure, advanced mathematics, probability theory and mathematics, linear algebra, engineering budget and so on. So personally, I think you are not suitable for this major. If you must take the exam, you still have to work hard. When you pass all the courses, you can get the diploma, so it is not difficult to get the diploma. You can measure this yourself.

Secondly, this diploma can only be said to be recognized by the state. Legally, they enjoy the same treatment as ordinary full-time undergraduate graduates. However, it may not be recognized in the actual society. After all, this is a second degree. I think the usefulness of this diploma varies from person to person. It's still very useful if there are people.

3. Add one extra point. The only advantage is that it is more convenient to take the civil service examination after graduation and is not limited by the same academic level.
