How often do you get a second shot?
Microsoft Learning has a great offer out at the moment which covers you for a second shot at an exam if you fail.
Now, I know personally that sitting exams is hard work, and the added stress if you don't get that pass the first time around is a killer, but this offer really provides a great safety net for those people who are eager to give the certification streams a red hot one, but aren't feeling fully confident.
Check out the link, and make sure you read the details, as there are certain requirements of the offer to make sure you can re-book for free if you should be unlucky enough to not pass the first time through. But hey, now is a great chance to take a double swipe at an exam, and who knows, for some of us, two's a charm ;)
