see-saw ride, ended smooth with

The See-saw ride as I was very confident when I appeared for the first time for SAS certified Visual Modeling and FAILED.
Yes, I failed in the first attempt and was very down as I don't know what actually went wrong. With the advice of a friend, I have started practicing here, the very first test was the eye opener as I went through the result with correct answers. I had to relook many topics! 
This practice exam helped a lot, thank you, appreciate the help I got from support team as well.
