I called Microsoft and Prometric, the information is different.
Prometric : between attempt 14 days no matter what between 1st and 2nd attempt or 2nd and 3rd attempt.
Microsoft : No wait period for 1st and 2nd attempt; and 14 days between 2nd and 3 rd attempt.
I also ask both of them to recheck the information, and they still confirm as above.
The reason that I ask because of the second shot that will end Jan 30th 2008.
So I hope I can pass some test on Jan 19th without worry about the confuse between Prometric and Microsoft.
If I can not pass, wish me luck for Prometric allow me to take second shot before Jan 30th 2008.
Thanks anyhow.
