After taking the Masters exam two weeks ago i felt that i had done good on the test when i was done. But when i got my results it said i had failed, i was on the phone right away, what i had done was when copying the answers from the work book to the answer sheet about half way thru i noticed i had skipped one and had dotted several answers in the wrong spot i went back and erased them .Not good.The scan tron machine picked up two answers per question and gave me a zero for each erased question.So i am just passing this on to you test takers dont make the same mistake i did and leave enough time to mark your answers in the right spot.After hours on the phone with the testing people its faster to just retest.
