Is there a DEV 531 Exam? I was studying for the 401 exam and noticed that it's not really development material. Not only that, but a certified admin at my company gave me the notes from the admin exam, and the "development" one is the same material with different wording.

If I'm going to get certified, I want to take an exam that actually deals with what I use. So is there a DEV 531 exam or something similar, that actually has Visualforce/Apex on it?

I am trying to develop an online exam.

I was successful in keeping all the questions and writing class for them.

It works fine, but I need some questions which should be randomly picked from object.

Every time these questions should be different.

How can we achieve randomly ques from db?

Help me out at earliest.
