Every year, educational institutes admit students under various courses from different locations,
educational background and with varying merit scores in entrance examinations. Moreover,
schools and junior colleges may be affiliated to different boards, each board having different
subjects in their curricula and also different level of depths in their subjects. Analyzing the past
performance of admitted students would provide a better perspective of the probable academic
performance of students in the future. This can very well be achieved using the concepts of data
mining.
For this purpose, we have analysed the data of students enrolled in first year of engineering. This
data was obtained from the information provided by the admitted students to the institute. It
includes their full name, gender, application ID, scores in board examinations of classes X and
XII, scores in entrance examinations, category and admission type. We then applied the ID3 and
C4.5 algorithms after pruning the dataset to predict the results of these students in their first
semester as precisely as possible.
