Data-based Smart test

A valid evaluation is an evaluation that lowers learning anxiety and motivates learning. The evaluation affects the learner's self-esteem, therefore, evaluation appropriate  to the educational goal and the student's level should be considered. We aim at quality evaluation and reliablity through data-based analysis.
