With the rapid development of training institutions, the market of training institutions is also mixed. At this time, you need to choose a reliable, reliable and responsible training institution. I think New Oriental Online is good. I have a friend who passed CET-4, but failed CET-6. Later, she enrolled in the online course of New Oriental, studied with the teacher for four months and passed the CET-6 successfully. The teachers of New Oriental Online are very professional, and the whole course is not available in 200 yuan.
