In this prediction model, the grades of 4,740 students in the first semester of the third grade were used. The number of variables were 98 and they were classified into three categories (school education, private education, background). Result of the study showed successful performance in other subjects, aiming at achieving post-graduate degrees and the ability of self-directed learning were presented as most highly relevant.
