Textbook Notes
Restore the teaching process and knowledge points in the classroom, and sort out and annotate the key and difficult points in the classroom. There is also a preview section and a sorting of the key and difficult points of each lesson, which can be used as a substitute for textbooks for previewing new lessons, as well as for pre exam review. Preview can be done until the end of the semester, and a complete solution can be provided in one book. Improve the quality and efficiency of children's classroom learning.
