1. Why should I minor in it? Minors are time-consuming, and many classes are arranged on weekends and winter and summer vacations. If you minor in the certificate, you can give it up because the employer is not interested in minor. If it is for further study, it is even more useless.
2. Why do you want to learn French? If you really like French, I suggest you go to a professional school like Shangwai, even if it is a training class. Because there is no French department in Tongji, it is not that the level of French teachers is not good, but it can be seen that at least the team of French teachers in the school has not been built. It's also a minor, and it may be better to minor in German.
3, combined with their own professional, first do a good job in career planning. If you are nervous about your major, or you need some certificates or there is room for improvement in English, and you are more utilitarian than interested in French. Then I suggest you don't minor in French.
When I was an undergraduate in Tongji, I minored in international business. Later, I gave up, because I think this major is not very helpful to my career planning because of the above three ideas. At the same time, it is time-consuming and laborious.
Think for yourself. You like reading. Anyway, I don't think it's appropriate, and I can give up. There is nothing wrong with trying more.
