摘要：A noval approach for checking of computerized multiple choice questions test (HCMCQST) like in NTS (National Testing Service, Pakistan), Engineering Universities and Medical colleges Entry tests without any errors is presented in this world. In this world tests are conducted in two ways; computerized /soft copy and on paper / hard copy. The NTS and Entry tests in Pakistan are conducted on papers i.e. answers that are filled by the contestants are on papers. The contestant has to fill the circles on the paper. The circles are sometime filled properly and sometime not properly. This also contributes in increasing computerized checking with errors. The reasons behind this that machine mostly don��t read the incomplete filled circles. When HCMCQST are checked computerized, there may be possibility HCMCQST paper may be damaged or bend or torn. In this condition checking done may carries some errors due to not proper reading of damaged area by computer. Thus final results don��t achieve the 100% accuracy. For this reason, an algorithm is designed that will check the HCMCQST answer sheet paper with computer. The efficient algorithm will remove the noise if there is in the HCMCQST answer sheet paper, and then HCMCQST answer sheet paper will be checked. The results make it more attractive for educational application.
