Online Test and Simulation Training Based on Three-tier Structure

Abstract This paper completes software system design and development of papers management, online test and simulation training based on three-tier structure, and focuses on the design and the realization of questions saving, randomly generation algorithm of questions in the network environment. Teachers can input and save questions at the same time. On-line test can be used for normal examination, and simulation training modules can provide students with opportunities for self-learning. Using system can improve the work efficiency of teachers and the quality of the examination.
