I took it and passed back in 03, I was testing at around 83-85% each time. The first half I blew through it(not much on bonds) and I rocked. Took a break and got a little too cocky before I took the 2nd half. The first 20 questions were all about bonds...I almost shit myself since bonds were what I had the most trouble with during testing. I made it through but I almost froze close to the finish.
The best advice I got before I took was from the managing partner of the firm I was with at the time.....see the pass he said. He realted it to racing and not focusing on the wall..if you do focus on the wall you will tend to drift right into it. DO NOT even one time mentally think of failing before you walk into the testing center. Take 30 min or more the night before you take it right before you go to bed or as you are in bed imagine yourself taking and kicking ass on the test. Right before you go into take the test again imagine yourself passing "see the pass" see yourself taking the test and clicking finished(if you take the computerized version" and a passing score hitting the screen.
I can't stress this enough. You know the material, you know how to pass...just go and pass it.
