E-learning systems are very popular and offer very useful method of learning. Tests in e-learning system can be created in various modifications. The paper proposes expert system and fuzzy approach for evaluating test completed by students. Proposed approach identifies criteria for evaluation of specific test and divides test into suitable categories of questions. Then, the test is created and shown to the student. After collecting completed test from student, the expert system with knowledge base is proposed. Subsequently, test is evaluated by expert system. Finally, the evaluation of test is visualized and shown to teacher or administrator of e-learning system. Particular steps of proposed fuzzy approach with expert system are described.
