This book is great! It expands and deepens the physics and electricity part of middle school. The content is very systematic and very helpful for children's physics learning. Moreover, the book has been adjusted according to changes in the examination syllabus, keeping pace with the times. I especially like the video explanation function inside, so children can better understand the knowledge points. However, I kind of hate a certain exercise in the book. It's too difficult. My children and I studied it for a long time. But overall, this is a very practical book, highly recommended!
