I suggest you choose more training institutions, preferably closer to home, attend more classes and compare more.
First of all, if you want to find oral training classes, you'd better choose those schools that specialize in oral training, because many training schools don't specialize in oral training. So you should pay special attention to this aspect when looking for English training institutions!
The second is to choose a training institution in the form of pure foreign teachers teaching in small classes. When learning spoken English, you must practice more. Therefore, when looking for oral English training institutions, we must choose English training institutions that teach in small classes. Because there must be enough opportunities to practice oral English, classes above 10-30 can't learn oral English well at all, because there is no opportunity to practice oral English at all, and teachers can't take care of every student.
Generally speaking, 4-6 students, or 6-8 students is the most suitable number, 10- 12 is average, but as long as there are more than 15 students in such a large class, learning spoken English is of little use. So when you choose an English training institution, it is most appropriate to choose a class of 4-8 people.
