Finally passed the Gwgk test after two attempts. Did quite well second try.

I did have one question about the test this time around. In the past Cisco exams I've taken, I knew that I had to wait a week before I could retake an exam if I didn't pass it. When I took the test today, I noticed at the last post-test exam screen that it said (as well as on my score sheet):
"Cisco policy requires that you wait a minimum of 180 days before retaking an exam (with an identical exam number)."
I don't remember seeing this before. I took this exact exam about 2-3 weeks ago, which I failed. Does this mean that I should have waited until July to retake it and this test is invalidated or something? If this information is correct, could Cisco possibly do anything better to *discourage* people from pursuing certification by insisting on waiting such absurd periods of time before being able to retake a test?
