An expert in the field, i was bored of giving exam in a pdf file. Frankly speaking, they do not give the feel and also, make you a procrastinator. This site is far better and in fact, the best that i have come across. There are random questions for IIBA, which prepares you for all kind of challenges you might face in the exam. Further, you get a report of your performance that allows you buck up and make the most of available time. Thank God, we have this site or else, nothing could have prepared me for the actual exam.
