Whether you need to go to an institution for training depends mainly on your actual situation. If the professional operation ability learned by the school can fully meet the job requirements, there is no need to go to institutional training. If the school is average and the teachers' professionalism and practicality are poor, and they can't fully meet the job requirements, then they can only continue to supplement and improve their professional skills. In addition, training institutions should be carefully selected. Choosing a lot of so-called training schools to teach things is no different from the depth of school teaching, and it is not worth the candle. I hope the above answers can bring you some help, and you can continue to communicate if you have any questions.
