In fact, to find an English training institution, we should not only consider whether the teacher is a real foreign teacher or an experienced Chinese teacher, ESL certificate, teacher qualification certificate, but also consider the number of students.

For example:

EF, Wall Street and other high-end oral training are all four-person classes+salon+man-machine dialogue, so it's good to go out and spend time studying outside.

New Oriental and New Waterway focus on exam-taking, which is generally a small class of 25 people or a large class of 100 people, but it is very effective for exams.

Lezhi online pure oral English teaching is a zero-based four-person class, and other eight-person classes can listen to it for free in public, which is more transparent and true.

In short, when choosing, you should choose according to your own needs. If you take the exam, the New Oriental Big Class is recognized. If you speak English, it is necessary for several people to have small classes. In addition, only consider whether the price is acceptable.
