To each their own. I know the CBA like the back of my hand and do well on standardized tests. I took the exam and finished in a little over an hour, looked around and though I was missing a portion of the test and asked a proctor since I was first one done out of 350 people. I decided to sit down and re-take it. I got the same answers and was still the first one done. They don’t tell you your score but i am pretty confident I aced it.
That being said, the passing rate is somewhat similar to a bar exam and the people taking the exam are mostly attorneys, so it is a VERY difficult test, with tricky wordings and crazy scenarios where you will have to know how to apply the CBA
