Design And Implementation Of Mock Examination Management System Based On C#

With the development of the information age, the paperless era is coming to us. Development of faster computer speed, various kinds of information can be transmitted over the network. From ancient times, the test has been an important way of selection of personnel, to the present from the imperial examination in the exam, college entrance examination, and now the bearer of various grade examination, the examination has now developed from paper to paperless exam. It can be said, must be the main form of paperless exam after exam, because with the improvement of environmental awareness, past examination form requires a lot of manual and paper will be replaced slowly; while in the past the teacher’s examination paper time will waste a lot of time, which has become a very troublesome thing, then have a exam, you can automatically test paper test management system is necessary.This design of the mold level test management system to help users successfully pass the exam system, there are four modules, each module is generated paper titled entry module, paper analysis module and system settings module. Paper Generation module is the main module level module test management system provides a paper generation features, including three sub-modules, sub-modules answer sequence, the whole truth simulation modules and sub-modules smart group papers. Wherein all true analog sub module uses composition based on genetic algorithm papers algorithm can be more efficiently produced Simulation Tests; smart group roll module focused on the wrong question generated into papers automatic composition, is about user wrong title number as a Important indicators.Title Input module provides two functions, namely, automatic crawler module with manual entry module, the questions are divided into two modes of entry, grade management system can periodically test mode from a network climbers take appropriate topic for building incremental exam provides a realization basis. Manual entry module is more flexible for the user, the user can choose the appropriate entry questions of title information.Test Analysis module is the system the more important module, which includes four modules, which are currently sub-module exam analysis, historical questions query sub-module, history wrong topic query sub-module and by probability analysis module. The first three modules are the subject of analysis of the contents of the display, vary according to the different requirements of the subject is displayed. By probabilistic analysis sub-module provides the user through the recent probability, in the form of a line chart display to users, vividly described by the possibility that the user change the probability of the user by constant practice process.This design of the mold level test management system to solve the following problems:1) How to generate compliant exams2) How to prevent a user after a system crash subject of loss of information3) How to back up data4) How to calculate the probability of the user through the testBy solving the above problems to achieve a good level of interactivity mode test management system for paperless examination we made some contribution to help users successfully pass the exam. Whether in the requirements analysis phase, the system is still in the design phase, herein are given in line with the requirements of the design software requirements analysis and system design.
