1, majoring in electrical engineering, I didn't understand the use of these certificates before, but I still took the exam, intermediate maintenance certificate for senior high school entrance examination and advanced maintenance certificate for college entrance examination, but these certificates are not enough. These certificates cannot be called electrician certificates, commonly known as operation certificates. We must take this certificate. Remember, we must take this certificate. Our major can take this certificate like a diploma, but it is not necessary.

2. All electrician's certificates obtained during the college examination have no effect at all in the work. If they do this, they will be charged with electricity and have a limit on their working years. When you are in college, you should get more scholarships, read more periodicals, publish more papers, and conquer professional English and professional knowledge with a little idealism.
