Effective is for sure. Squirrel Ai intelligent adaptive education is a very advanced teaching mode. It is a dual-teacher model of "artificial intelligence+real teacher", and the knowledge points are divided very finely. Through the AI system, the mastery rate of knowledge points is measured, the weak points of knowledge points are accurately located, and the teaching explanation videos are pushed synchronously. The course is tailored to the students' situation and the teaching content is targeted. After just three months' study, my child's English score has improved by 2 1 point, and I have also communicated with other parents of children studying there. Other parents also said that the squirrel Ai teaching effect is quite good. After good academic performance, I naturally became interested in learning and became more confident. Thank you for your question. I hope it helps your problem.
