If you focus on the basics. You can choose some explanatory review materials, or combine lectures with exercises (materials with explanations and support links). For example, the complete interpretation of the new textbook is still very detailed, which is very suitable for the relatively basic review stage to help you sort out the knowledge points and better master the knowledge points. Mastering basic knowledge is very important for college entrance examination scores.

If it is the consolidation stage of practice, you can choose relatively difficult materials, for example, you can choose some real questions and simulation questions to do; For example, the "five-year senior high school entrance examination and three-year senior high school entrance examination" and "topic help" are all new and have a wide range, covering the common, easy-to-make, important and difficult points in the college entrance examination. If you feel that it is still a little difficult to master the basic knowledge but do the real questions, you can choose "zero mistakes" as layered training to help you consolidate the basic knowledge, then practice the key and difficult points, and then practice the error-prone points.

It depends on your specific situation, and I hope I can help you.
