|Project Description: ||This project is a comprehensive application for conducting online tests for Physics students enrolled in courses managed by the Texas Electronic Coalition for Physics (TECP). Online Grading System (OGS) is developed for the Department of Physical and Life Sciences of Texas A&M University - Corpus Christi. OGS provides Web-based interface for instructors, students, TECP coordinators and chairperson. Five Universities in Texas will be offering online tests for physics courses to students through OGS. OGS provides dynamic generation of tests which have questions with variables in them. The values of the variables are unique for each student and are generated on the fly. Each question can have an image associated with it. The values on the image too can be generated dynamically. All the dynamically generated values for each student are stored for future reference. Solutions too are computed by the OGS dynamically depending on the random values and formula. The solution keyed in by the student is compared with the solution generated and the score and letter grade are assigned to each student.
