Microsoft is trying to entice more people with their Second Shot program. If you sign up for this program Microsoft will give you a free second change to take a certification exam if you fail it. I have signed up for this in the past, but never actually used it (hehe). Well this program is now even better.
You still get to retake an exam if you fail it. But now there is an incentive for people that pass the exams. If you pass you get 25% off the price of the next exam that you take. If you take alot of exams like I do, this is a nice little benefit.
Have fun with your testing.
