I was not referring to the AGCT alone.  
.
Where I went to school, there were a handful of really smart kids who recognized flaws in the standardized tests. E.g., discussing the test in class over the next few days, a smart kid would point out that "The correct answer could be A but it could also be D." What? Howzat? "A follows from linear thinking but D is also correct if you take the sum of the cubes of each part."  "... C is correct but B is just the mirror image and is also correct." And so on.  
.
SOME of those smart kids got stuck on the ambiguities and sometimes put down the "wrong" right answer and didn't score well. OTHER smart kids recognized the ambiguities but knew that, of the two right answers,  A is the answer they wanted and would be scored as correct.  
.
Smart grownups taking the AGCT fall into similar categories. Some see correct alternative answers but don't score well because of that. Others see lots of correct answers but figure that thinking outside the box is not a desirable attribute in the military so they deliberately choose the "wrong" right answer and get rejected.
