Zero-based English course is suitable for students with weak or even zero English foundation. When you enter school, the teacher will give you a proficiency test, which will judge whether you are suitable for this class or a higher class. This is the most basic and important.
Then, when choosing, it depends on the curriculum, because students with zero foundation especially need patient guidance, and it is always not as simple as doing some homework after class, so choose as many learning courses with teachers as possible, and the teachers will guide you throughout your study and keep abreast of your progress, so that the learning effect can be better presented.
The teacher's guidance is mentioned above, so the teachers and structure of the course are also very important. In some schools, there is generally only one teacher in a class, so it is difficult to evaluate how each student is doing. Some schools will form a golden triangle, where Chinese teachers, foreign teachers and coaches perform their duties and care for each student seamlessly, which is also one of the important guarantees of learning effect!
If you can, you'd better go to school to see the environment and learn more before you decide. After all, it is really not easy to find time to study when you come out to work, so you should make a good choice. Come on!
