It depends on the teaching effect. Tell me about my experience. With fish for 1V 1, the course is 30 minutes shorter than the other two schools (and the course price is not cheap). Although the interaction is frequent and the atmosphere is active under the guidance of the teacher, it is not good to find that his English translation is pure Chinese translation. Vispark, a domestic spark thinker, has been doing domestic mathematics before. Although it claims to be the cooperation between the two companies, it feels a bit far-fetched and chaotic. Their family's curriculum is a small class of 1-6 students, and the courseware is all in English, which is particularly unfriendly to domestic children. As for Mathplore, they should be the first company to do international online education. His family is a small class of 2-6 people, and each class lasts for 40 minutes. You can also choose bilingual teaching in Chinese and English, and the form is also animation. At that time, I experienced it and found that it was the one that best reflected the CPA teaching method in Singapore. Generally speaking, Mathplore gave me a particularly good impression, whether it was the sense given to me by the customer service and the teacher's service attitude, or the actual experience in class. At present, the unit price of this class is the lowest among the first two, and the purchase of teaching materials is accompanied by materials, which can be said to be the most cost-effective.
