This system is based on our realities, at the request of our college academic and information engineering department, with the support of its design and development, Major is to complete our public elementary courses and cultural foundation online examination and hope that through this practice, and constantly design and development of a number of other courses online examination system.Through the analysis of the demand, structural analysis, the database requirement analysis, the system should have the final portability, convenient maintenance and updating, thus using B/S three structure models. Server - side design using SQL Server2005 database system and ASP.NET C# language.

These include add, delete, update, modify, and so on.On-line test module design mainly include(:1)The students register, registered user login is a verification process, the most important issue is to ensure the security of the whole system, users need to fill in the correct user name, password, and build verification code can log on to the system of related operations.(2)Retrieve password : college educational administration system requires students to do some actions modify basic information or login time, there is always a large number of students forget to look for administrators query code, such things are common. moreover, a term, the institute arrangements for most large - scale examination, which is a two - time, in order to avoid the students again forgotten password in the design, add " forget " this function.
