There appears to be two versions of the test - one that is heavy on questions related to options contracts, and another weighted toward questions on municipal securities. In my diagnostic tests, I was consistently doing well with options ... but struggled with questions on municipals. As luck would have it - today's test was loaded with questions related to those accursed munis.
Two and a half hours into the six-hour exam, I answered the last question ... and not with insubstantial fear, I hit the 'grade exam' option.
I passed with dozens of points to spare. Oh man, that's a weight off my back.
Now if you'll excuse me, I will be taking a few celebratory drinks with some good friends ...
