Generally speaking, there are several points.

1, it depends on which teacher the teacher says, because there are good and bad minor teachers, and good teachers are worth listening to. A bad teacher is bored and can only sleep. . Moreover, some teachers can speak dialects and don't understand them at all. . I met one. .

2. Whether the minor is useful depends on the personal nature. If you study hard and put your heart into it, you can naturally learn a lot, but it is of course useless to sleep and play with your mobile phone. The minor will play a certain role in applying for double degrees, applying for graduate students and finding jobs, but it is not decisive, just a reference, because the minor is not as high in teaching quality as the compulsory course.

3. What do you mean you can't hear? Can't you hear the sound? Generally speaking, the number of minors will not be too large, unlike a school that chooses 200 to 300 students, the minor will usually be 30 to 60 students, so there will be no problem that you can't hear.

What courses to choose mainly depends on what you like. But you should also consider what your major is now. For example, if you study philosophy and want to minor in shipping, your professional knowledge is too different, so it will be difficult to learn. However, if you are a ship and want to learn philosophy, you can learn it (but it seems that there is no minor in philosophy, just an example). )

Personally, I suggest that you sign up for a minor if you have spare time, because after all, most minor courses are on weekends, so it is good for your future not to sleep late to go to class. As long as you are careful, it will be useful.

6. The minor exam is generally passed, and the teacher is not very strict about the exam. It's no problem when it's full.

I have written so much, I hope these summaries can help you!
