These two exercises have their own advantages, mainly depending on the students' foundation.

For students with weak foundation, Wan Wei is better; For students with a certain foundation, May 3rd is better.

Wan Wei is more inclined to basic knowledge, with clearer explanations and more novel and comprehensive topics; Pay attention to the foundation and improvement in the "Five Nights" and "Three Nights", which is slightly more difficult than that in Wan Wei. Therefore, it is suggested that students with weak foundation choose Wan Wei, and students with a certain foundation can consider using Wusan. No matter which one you choose, you should pay attention to the consolidation and improvement of the foundation and use the questions and knowledge points flexibly in order to achieve good results.
