</div></div></font></blockquote><div><br></div><div>That&#39;s similar to what I was saying before about measuring the content of an expected answer and ensuring consistency.  Sounds easy in theory, but not so much in practice.  (In theory, theory and practice are the same; in practice, they&#39;re different.)  I also wonder if balancing the questions on any given test by weight/content wouldn&#39;t interfere with the randomization, making certain questions more or less likely to appear on a test.  I&#39;m open to suggestions on whether this is an issue that needs to be addressed, and if so, what the right way to adjust things might be.  (I mean, for example, if you would like to see questions weighted by content, then propose a means for measuring the content of a question.)</div>
