Abstract—Online examination system has been developed as per requirement of NASSCOM and DIT . The system can cater to a large number of students for administering multiple choice questions and True-False Questions of various subjects. System offers Dynamic paper generation using 3 parameter model based on Item response theory. Flex, Spring and Hibernate frameworks have been used for development of system and it is highly secure and fail safe. The system uses open source stack in its design and is extensible, reliable and scalable to handle future requirements. The system is further designed to support very large load using cloud computing paradigm. The paper presents the functional descript ion and architectural design of the system along with Adaptive exam conduction model used.

Index Terms—Online examination software, flex, spring, blazeds, terracotta, hibernate, eucalyptus, cloud computing.
