Data mining is an analytic process designed to search through a large database in search of consistent patterns and/or systematic relationships between variables among data. Decision trees are one of the models that can be applied to data mining. There is another important model used in data mining for prediction called \"Naive Bayes classifier\". This paper is an attempt to help prospective students to make wise career decisions using these data mining tools. A student enters his entrance rank, gender (M/F), sector (rural/urban) and reservation (OBC/SC/ST/GEN) category.
