Examination is a most important factor in determining the performance of a student, so the answers scripts are evaluated to measure the performance accurately to estimate the understanding level of a student. But there are so many errors occurring in the evaluation of the answer scripts. There are so many automatic answer scripts evaluation systems which use techniques like Optical Character Recognition, Basic Elements, etc. and technologies like Image Processing, Neural Networks, etc. in which each has certain defects. Some system does not support meaning wise analysis, some do not allow semantic analysis, some of them are more time consuming. In this paper we can overview the factor that makes the system ineffective to use
