If you want to choose the service quality of a training institution, there are four points to pay attention to: 1 To choose professional skills training, you must first understand the employment situation and salary of the fresh graduates of this institution, because the purpose of your training is to learn technology, get employment and earn money, not to watch advertisements, but to see the results. You should go on a field trip 2. Don't look at the scale. If the mountain is not high, there must be a fairy, and if the water is not deep, there must be a dragon. 3. Look at the teachers. A teacher is not necessarily a professor. Only teachers with real industry experience can impart the most practical skills to students. 4. Compared with fees, the fees for the same professional training are 2-3 times worse. Choose a training institution with compact curriculum, short study time and low cost. This is a cost investment.

The above is my experience, for reference only.
