My son went there to study for some time. At first, he felt that the effect was average, but later he found that it was not the poor teaching quality, but the poor foundation of the children. I really appreciate the patience of the teacher. I think he had a headache, and finally his grades improved a lot, and he didn't spend money in vain.
Advantages: The teacher is patient, earnest and responsible for the children.
Disadvantages: it's far from my home, but the elevator is slow.
