Abstract: To make it possible to accurately determine a learner's degree of understanding.SOLUTION: A learning system 1 comprises an image forming apparatus 10 and a server 300. The image forming apparatus 10 transmits, to the server 300, answer data obtained by a learner solving test data for checking (including answers and answer time). In the server 300, a correctness determination unit 355 determines whether the answer is right or wrong, and an answer time determination unit 356 determines which one an answer time is within an answer set time, within an allowable time subsequent thereto, or a time exceeding the allowable time. (i) When a result of the correctness determination is correct and the answer time is within the answer set time, an understanding degree determination unit 357 determines the learner's degree of understanding as a first degree of understanding indicating that the degree of understanding is sufficient; (ii) when a result of the correctness determination is correct and the answer time is within the allowable time, determines as a second degree of understanding indicating that the degree of understanding is lower than the first degree of understanding but exceeds a reference value; and (iii) when a result of the correctness determination is wrong, determines as a third degree of understanding indicating that the degree of understanding is insufficient.SELECTED DRAWING: Figure 2
