TeXML

This class helps to make the process of taking online tests, surveys, questionnaires very easy. It handles everything from creating the questions down to randomly assigning the questions to candidates and finally calculating the scores. The best thing about this class is it stores the questions in json format (in a json file) in form of subjects. This means you can handle enjoy everything if you prefer to use javascript or jQuery depending on your taste. To fully understand how this class works you need to go through the files in the example directory from both your browser and text editor (the comments are more useful, I think)
