Zhikang education is good. It is a one-on-one institution, learning and thinking. Most teachers are experienced teachers. They have a good reputation in Beijing, much better than studying. Learning is mostly advertising, and the strength of a real teacher is not as good as intelligence! I recommend you to go to Zhikang Education. Now teachers can choose online. You can go to the advanced website to learn about it and get a general understanding of the actual situation of the teacher. Zhikang's selection of teachers is very transparent.
