Hi friends,
i m working on online exam project in which each question has
difficulty level in percentiles.i m using servlets to do this
since i want to display one question at a time ibn browser.
if you are aware of GRE adpative testing it's the same thing
that i want to do..
At the start of exam i will ask some moderate level questions and depending upon the user response i have to decide the difficulty level of next question. so if his intermidiate score is the diciding thing which will divert him to low difficulty level question or higher difficulty question.
by the time i was surfing i come to know that this is called as
'Item Response Theory'
now my difficulty is that how should i implement this in java..
i m giving u link.. http://ericae.net/scripts/cat/catdemo.htm
if anyone is having any idea please tell me..
Thankx in advance..
Bhupendra

Well, when I did this for LANWrights adaptive tests, I made a class to hold a question with variables for how hard, what topic, the question text, etc etc.
I populated the set of question objects from an XML script (so easy to edit!)
