How was their system scammed?

The same way it's always done with exams, test takers quickly write down all the questions they can remember after the test.  Nowadays camera phones can be used to copy tests.

Then the questions are all gathered eventually from various cooperative test takers and a list of question and answers is made that can be memorized by people who don't know anything about the skill or knowledge  being tested.

Civil service undermined, corruption riddles the system from the inside.

  When the dumbest and most corrupt make it to the very top using the scamming, your empire is doomed.  Sound familiar?  

Kind of how duuhbya graduated from the Ivy League?

Standardized testing like IQ tests and SAT, and  no child left behind multiple guess ed..jee...kay..shun.  Opens the quality control to this flaw.  

Real education instills real knowledge.  That makes for a creative productive culture.

Neil Bush even set up a test cheat company (with Saudi funding) designed to drill kids to pass the standardized tests of no child left behind.  It costs 40 bucks per student for the computer software, call your school today!

Your children need the best!  Designed by a Bush to beat the Bush test.  Will your kids be ignorant enough to suceed like the bush boys?  one can only hope.
