Question on graduation rate

<p>Truman has a low 4 year graduation rate - I think US news has 36%, I may have seen as high as low 40%, if memory serves me correctly. </p>

<p>One person I've spoke with thought the low graduation rate might be result of 5 and 6 year programs?? </p>

<p>Any idea of the probability an excellent student would need to take more than 4 years for graduation? I know (many, many years ago) I had to go an extra semester as the first course in my major was filled.</p>

<p>He will have 6 AP credits . . . so that would help, looking at computer science major.</p>
