I want to improve children's thinking ability. My friend said the whale wisdom course was good. I wonder if there are any free audition courses?

It's really good. Before signing up, you should also attend the audition class, especially the teacher's attitude towards class, game textbooks and children's liking. There are basically small classes here, and the teachers' class ability is also very good, which can improve children's thinking ability in happiness. He is also an old-fashioned children's literacy education institution. It has been more than 20 years, and they pay attention to cultivating children's all-round ability. I heard that there are quite a few people who signed up, and the effect is quite good. Parents can take their babies to have a try.
