Learning plusapp is a streamlined learning and education software, which educates users through online teaching, breaking the traditional teaching methods and meeting the teaching needs of some schools. Students can learn by watching videos on the platform, such as required courses such as Marxism, and get credits after learning. The platform will also score students, and there is no need for extra classes in schools. Combining online and offline, the platform can view the learning progress and the completion of the total course in real time.
