Microsoft is offering a free second chance to pass that Microsoft Certification exam as well as a 25% discount on an additional exam.  You better hurry though as you have to sign up by December 31st. 

Second Shot now gives you two incentives to get certified!

In the real world, you might need more than one chance at certification. With Second Shot, if you do not pass a Microsoft Certification exam on your first try, we’ll let you retake the exam for free.

As an additional incentive to work toward a Microsoft Certification, from October 15, 2008, to December 31, 2008, if you pass a Microsoft Certification exam on your first try, you get a 25 percent discount on a different exam.
