I am looking for an online examination system in which admin can post questions subjcet wise, questions may be descriptive with answer required in text input box or multiple choice type. A user will be able to login and take exam only after that his registration is activated through admin panel. Also when a user is appearing for exam the questions coming to him is of adaptive type like GRE/CAT exams. Result will not be displayed to him only the relative score will be displayed to him. This website will be hosted on the linux server , coding will be done in php and mysql will be used as database.
