Project Description

This is a project we made in ASP.NET. Its an examination system made in Visual Studio 2008 using a MySQL database. Please do take a look at it and suggest improvements. Also, if the project is vulnerable to any security threats, please do ping us back.

I hope you will like our attempt at coding this application.

Features-

User first needs to supply valid credentials to begin the test.

Randomly chooses 5 questions from a database of 10 questions.

The test is a timed test, admin can change the duration of the test before it begins in the code.

Test-taker can leave a question un-answered and come back to the question (if time permits) using the ‘Previous’ and ‘Next’ Buttons.

Code Details-

1. Login is authenticated against a MySQL database.

2. AJAX is used for the timer, allowing only the timer label to postback to the server each second.

3. Use of the Random class to generate 5 questions out of the 10 in the database.

4. Session Management using Cookies and Session Variables.

5. Use of javascript in the master-page to prevent the ‘Back’ navigation from a page (clearing the cache) [Would love your suggestions on an alternative to this]

6. Once the 5 questions are chosen randomly, they are held in a DataTable. This is then held in a Session Variable to hold the values during postbacks.
