What you want to ask is whether it is better to brush the questions or sprint at the end of the term 100? Both books are very good.

The high-level brushing of "math must brush questions" can help children review what they have learned, thus better consolidating knowledge points. The more questions they do, the stronger their knowledge.

The final sprint 100 has a wide range of questions, including multi-project special training and thematic integration. You can do critical exercises for some weak points, unit training can consolidate and learn new things in time, and it is also very suitable for brushing questions and can quickly supplement your own questions.
