In many universities, a student has to take several mandatory courses and some elective courses which the student can individually choose. Many a time, elective course contents are not clear and prerequisites are not seriously considered. In this paper, we show that it is possible to get insight into the student’s performance in the electives offered, by the knowledge of student’s past performance in related courses. Data of similar students, who have recently graduated, is used to build a decision support system (DSS) using decision tree and fuzzy logic. Rules are extracted that establish the relationship between prerequisites and elective courses and their performance. Current course performance is entered into this elective course DSS (E-DSS), which can predict suitable electives and how the student might perform in those electives. Satisfactory results are obtained from the tests, and it is found that the students who performed successfully well at the required prerequisite courses have also performed well in the related elective courses.
