On the whole, the difficulty of the topic of "Five-Three Excellent Papers" should be flat, and the difficulty of the topic of Sunshine students is slightly simpler. All-in-one test paper is more suitable for children with weak foundation in school, which can be used to check leaks and fill vacancies, review and consolidate their use. Sunshine students are a little more difficult, which is more suitable for students with good school foundation to supplement their exercises.
