1, whether it is formal, whether it has teaching qualifications, an excellent teacher team and a fixed teaching place. See if this institution has practical training, how many teachers in this field are full-time teaching teachers, because part-time teachers are probably just visiting teachers, and some even just hang their names in this institution and don't come at all.
2. Both face-to-face teaching with lecturers and remote video teaching are very important. In some institutions, there is only one teaching assistant in each class, and these teaching assistants are often quite low, which seriously hinders your learning process. Know that training institutions can ask to see the class environment. I think Xingyuan Design has done a good job in this respect, because their classes are still relatively rich, such as live lectures, face-to-face lectures and so on.
3. Pay attention to the reputation of training institutions. When Baidu searched for a bunch of negative news or a large space, it was confused by the water army, which was generally unreliable. Word of mouth depends on students' recognition, not covering up the negative.
4. It is easy to understand whether there is a free audition. Some institutions urge you to sign the contract as soon as you come to the door. Why? I'm afraid you'll run away after seeing the truth, so be on your guard once you meet someone who directly signs the contract.
