I remember when I came to the company for an interview a few months ago, the boss told our department manager that the child was good, studied well and had strong working ability, but the manager was thinking, who hasn't been to college? Many people who study well in universities have high scores and low abilities, so a smart boss will not praise you just because of the certificate you gave him, but depends on your personal ability to deal with problems.
Come on, remember that the person who wants you to write the certificate is yourself, because you really exercised your ability when you obtained some certificates, so these certificates are valuable.
