The key to oral English depends on which teacher. The level gap between teachers is not small.

Ask the teacher what it is before signing up.

In your case, go to New Concept 3.

There are two kinds of slow intensive courses in winter and summer vacation, as well as all-round listening, speaking, reading and writing (oral English is very fast, 12 days to finish the whole book, but I don't know if I can finish it ... I am taking this course now, and the time is almost two-thirds, but the course is only halfway through ...)

You can choose the new concept of 3+2+ 1 on weekdays and weekends, which is more comprehensive.
