Little brother, your long list of questions is really difficult to answer. Because everyone knows little about other majors except their own, and it also involves the question of where to find a job. It seems that I have to consult my seniors and sisters who graduated from various majors. As far as I know, the score of statistics is very high (relatively good), and the postgraduate entrance examination rate of environmental science (new major) seems to be the highest in the whole school. The learning environment is ok, quite quiet. What I want to say is that it's up to you. It doesn't mean that you will be assigned to work where you study. What's more, I suggest you go to Caida's website and ask clearly, because the chance of meeting you here is very small. Or go to its post bar and ask it.
