1. Champion class provides a real-time interactive learning environment. Students can interact with teachers and other students, ask and answer questions, and increase their participation and interest in learning. There is less interaction between teaching materials than the top class, so the top class is good.
2. Through practical operation and experiment, the top class provides students with practical opportunities to apply what they have learned, and cultivates students' practical application ability and problem-solving ability. Teaching materials have less opportunities to help practice than the top class, so the top class is good.
