If I say that the place where I spend the most time is the fire engineer's certificate, it is really difficult to take the exam. I have been planning to take the fire engineer's certificate for half a year since the second semester of senior high school, and then I began to learn all kinds of books about fire engineers. In the next semester of my senior year, I'm not entirely sure I can get in. To be exact, I should be a fire engineer when I graduated from college, but I was admitted. It's really too difficult. The pass rate of this certificate is only about 1%.
In my opinion, the most useless is the Putonghua certificate. I really don't know why our school requires us to take the Putonghua certificate. Moreover, my Mandarin is seriously nonstandard and my dialect is very strong. "I will leave home when I am young, and the local accent will not change my hairstyle." What I want to say is that I will never change my dialect, because dialect represents the people in my hometown, and I am the people in this place.
If you want to get that certificate in college, you must be selective. Don't take all the certificates, but choose a certificate that is helpful for your future employment and work.
