A learning service method, a server, and a system using a video are provided to enable a user to fill in test answers for previously suggested test problems, after the user views all of videos, thereby offering predetermined costs to the user according to evaluated scores by evaluating the test answers. A wire/wireless communication network(120) provides a network capable of communicating in a wire or wireless way. A user terminal(110) demands a learning service to receive the service. Videos, test problems and model answers for the videos are stored. A learning server(140) receives test answers for the test problems from the user terminal, evaluates the test answers by using the model answers, and transmits evaluated scores to the user terminal. |
