PSOL, see Please See Other Line

So I just got done taking an open book test. Which I'm grateful that it was open book, but it made me realize another thing that doesn't make sense to me. Why is it that when I look up something like UAT in the index that it can't just simply give me the page number right there? Why is it that it has to waste my time, not to mention the ink, to print "UAT, see User acceptance testing" and refer me somewhere else? Sometimes it's on the line above or below the acronym that I was looking up. When the test is 60 mins. long and there's 50 questions I don't have time to look in two places for the page number.
