Hello, I would like to ask which is better, the key points of Band 4 or the notes in Huanggang class. Compared with Huanggang's in-class notes, Huanggang's in-class notes are better in grade 4. Huanggang's in-class notes pay attention to the implementation of each knowledge point, which is of great help to the fourth-grade students to lay a solid foundation and improve their ability development. Emphasis is only on the key points, without strict details. Therefore, compared with Huanggang's fourth grade in-class notes, Huanggang's in-class notes are better.
