Microsoft has introduced their Second Shot Offer again. Using this offer people who are interested in doing certification get a second chance to that the exam if it does not go well the first time round. More details on this offer can be found on this page (http://www.microsoft.com/learning/mcp/offers/secondshot/default.mspx) .
It is thanks to this offer that I started doing my Microsoft certifications back in 2006 because in Mauritius exams are quite expensive (about $125/MUR3,500) and I would never have had the courage to spend so much money on exams if I didn't ave the second shot as a back up.
There are also 2 other offers concerning exams for SQL2008 and Visual Studio 2008 on the page. These 2 offers give you a 40% off voucher on any one of the new certification exams on SQL2008 and VS2008.
