Grading devices are expensive causing budget waste, in addition some are difficult to use. Therefore, an objective test grading system via Android mobile phone was developed to save cost and time in grading. The system uses image processing technique developed by Java. A camera on a mobile phone was used to capture the edge of answers and an equation of geometric simulation of digital camera sensor was applied to identify answers selected from calculation of pixel intensity in real time. The objective test grading system via Android mobile phone can work effectively and accurately more than 95%.
