The ape course is a good one. It is divided into two subjects: mathematics and Chinese. There is a description section in front of each book, which lasts for 28 days and lasts for about 20 minutes every day. It takes three weeks to consolidate old knowledge and preview new knowledge. There are knowledge maps to help children review before consolidation exercises, and finally there are exercises to help children expand their knowledge. According to the progress of the textbook, the knowledge points of last semester were comprehensively scanned, and the key points and difficulties were also compared. Very good.
