In the Microsoft Certified professional sense that is. I've taken over 40 of the exams since 1993, and I haven't failed one yet so I'm a bit nervous of doing an exam that might spoil that record. More normal people worry about doing taking the exam too early and then having to pay to take it a second time. So Microsoft Learning and Prometric have brought back Second Shot, a programme we ran last year.
From September 15, 2007 to January 31, 2008, we are offering the chance of a free second chance to pass a Microsoft IT Professional, Developer, or Microsoft Dynamics certification exam, if you fail it the first time. Details are on Prometric's site
