    In the field of education, the examinations are the process of evaluating the knowledge or skills of a student. And the methods for this evaluation always remain in discussion to make it even better and easier than before. Traditionally the exam evaluation is carried out on manual basis which is authentic; but quite time taking. With the recent developments in technologies, every step is taken to automate the current manual processes, to make the job easy and interesting for the human. Short questions - answers are playing important role in the evaluating of subjective knowledge so we have developed an application to evaluate the closed short question answer. Motivation behind the development of this application is to decrease the work load of teacher and the time required for the evaluation of the exam papers. Our application evaluates the answers by semantic matching student answers with the sample answer set by the teacher. And for the text matching between student answers and sample answer we used direct string matching and existing NLP(Natural Language Processing) algorithms like N-Gram and Longest Common Subsequence (LCS). The dataset for the experiments, consist of 100 short questions with at least three possible answers for each. Result showed that LCS give best accuracy when change is answers based on synonyms.
