Hello,
I am an experienced Java developer, I can do this project for you.
I suggest you to develop this web application in java using google web toolkit tehnology.
I is a framework to develop java web application fast and secure.
Or if you want only JSP standard web java tehnologies I can do it too, but it will take more time( but no more than 10 days).
I can provide to upload data from word, excel and any text document only to respect a specific format standard, or I can build a java interface to add different types of quizs.
Please let me know if you are interested. And to specify how to do you want to do it.
