In the written exam,the content consists of"Information systems Technology"in complulsory modules,"Networking Technology","Multimedia Apply", "Algorithmsnd Programing","Data Management Technology"(choose one from four) in elective modules.The test covers the operation questions about Word, Excel, FrontPage, PhotoShop, Flash,Access and VB.The exam paper includes compulsory part and elective part,and in the electibe part it has an operation about choosing one from four. Compulsory part ,it contains three operation questions about Word and Excel,and it has two operation questions in elective part,each is ten scores ,the total score is 50.The purpose of the exam system research is to develop a information technology rank examination operation systems.The system includes teachers' end and students' end.The teachers' end finish the task of exam management,results statistics and paper's assessment.
