WelcomeToOnline_Examination

Introduction !OnlineExam is used for distance learning. Administer exams and qualification tests or review quizzes in a secure client server implementation using either an internal server or Internet/Intranet linkage.
AUTOMATE THE TESTING PROCESS
With OnlineExam you can create and administer exams, tests or quizzes in a secure client-server environment. The system is web-enabled so you can use either an internal server or link up over the Internet or an Intranet. No programming is necessary. Just input your questions, select the answer type such as Yes/No, Matching, Multiple Choice, Text Answer, True/False, or Numeric. Those being tested scroll thru the exam questions and respond online from their home computer or workstation. Once the test has been distributed, completed submissions are electronically sent to the OnlineExam data processing engine, which stores, scores and tabulates them. Results are published by the reporting module. Detailed records of all data turned in by each respondent is readily accessible by authorized users from the OnlineExam SQL database. Thats how easy it is!
