Reminds me of when I was teaching and we were discussing test design. If 90% of your students fail your exam what have you learned?<p>I would argue that barring a conspiracy of some kind that the designer has made a mistake in either in the preparation of the exam or the preparation of the students. Others might argue that students may be lazy or aren&#x27;t maximizing the use of their time. I hear similar arguments about users now that I&#x27;m in IT but I&#x27;ve always felt that it is the designer&#x27;s problem if &quot;no one can use it right.&quot;
