Students modeling is an integral part of any form of education and this becomes more challenging with the advent of new tools of ICT especially Intelligent Tutoring Systems (ITS). Educators must have to take help of such tools to identify the curriculum gaps towards Outcome Based Education (OBE). One of the ways to reduce such gaps is to identify the personalized requirements of tutorials for learners after going through some topics divided into subtopics. This paper proposes a technique to identify the personalized tutorial gaps by analyzing the responses provided by students against MCQ type questions. The proposed method has been implemented within a web based environment. Prototype of the tool having integrated with the proposed method shows that the students can identify their tutorial requirement without the help of human tutor and hence discovering the student's understanding.
