First of all, school facilities, computers and later equipment, and more importantly, teachers are now paid a high salary.
But the same, find a stable job after studying, and the tuition will be earned back soon.
Give some advice:
First, when choosing a school, the landlord must carefully read some foreign teachers or various experts written in the school brochure to see if they are simply nominal and whether these teachers can't come to teach locally.
Actually, I don't recommend having foreign teachers. According to what you said, your brother's English level is definitely not up to the point where he can communicate with foreigners smoothly, so the foreign teacher can't understand it in class, and the translation can't fully express the meaning of the foreign teacher. Foreign teachers are simply chicken ribs.
Second, we must see clearly whether these training institutions have their own production departments.
This is very important, because the production project can prove the strength of the teacher and ensure the production level of the teacher.
And students have the opportunity to directly participate in the company's production projects.
And you have to see clearly whether these production departments belong to the training institutions themselves.
Some schools pretend to be foreign companies, but it has nothing to do with it.
In short, be sure to keep your eyes open.
