I studied IELTS in Patterson English, and it took me nearly 65,438+0 months to improve my score from 5 to 6. They teach one-on-one, which is much more targeted than the big classes in New Oriental, and I think their teachers are also very good, especially foreign teachers. If you can afford it now, I suggest you consider one-on-one courses. It is too difficult for large classes to improve their grades.
