The qualification certificate only proves that you have such a level. Moreover, at present, the real gold content is human resource managers, engineers, accountants and tax agents recognized by the state, but they all have to be above the intermediate level. These countries have incentives.

The professional certificate of a general school does not contain much gold, but it is also a proof that you have studied. If you are competent, you have the corresponding intermediate level. Advanced certificate is better. However, if your actual ability is average, you can take the exam, but if you pass the exam, I suggest not to show off, because it will be embarrassing.

Qualification certificates are also useful for work. However, it is recommended to take the relevant certificate of your future career planning. In other words, if you want to know what you want to do in the future, then a certificate or something will serve your future work. Otherwise, it is a waste of time.
