I think this problem should be analyzed in detail.

Because some majors are really busy in college and have heavy learning tasks, they have no time to study the second major. In my opinion, universities should learn their own majors well. If they have the energy to study other majors while learning their own majors well, they can take a second degree. If you are busy with your major, don't take a second degree, because it may make you have less time to study this major. For a long time, the second degree will not only cost you money, but also affect your first degree learning process. If you choose, you should work hard to do better. Some people think that you can not be serious about your second major, but you should be clear that when you graduate to find a job, many people in this major will compete, so you should also be in awe of your second major.

if your major is not very busy, you can take a second degree. As the saying goes, it's better to learn more than one skill, take one more course and take one more certificate to enrich yourself, and it will provide a broader road for you to find a job in the future. When you choose your second degree, you should first consider whether you are interested in that major, then the teaching arrangement of this major, and finally the career prospects. I remember when I applied for the second major, my mother asked me to apply for a second major. She thinks that if she can learn more things in college, it will be beneficial to her own development, but my major is busy, and I usually have more homework and social practice, so I didn't apply for the second major. I suggest choosing something related to my major as the second major, so it is easier to get started.
