I also wanted to study for a second degree at that time. At that time, I asked for Band 4, while Wuhan University was Band 6.

There is no limit to what major to choose. The second degree seems to be two years, and the minor mentioned upstairs is to study for one year and then get it without continuing.

As for your shortcomings, it depends on the individual. The seniors and sisters have different views, and the friends around them feel different. As long as you think you really have the strength to learn, then learn at the expense of the weekend. And I think whether to take the second major or not and what major to choose should be related to your future planning. For example, I have a classmate who wants to change his major after taking the postgraduate entrance examination, so he chose International Trade as his second major. So we still have to consider it comprehensively.
