Are you taking Microsoft Certified Professional exams with Prometric between now and 30 June 2011? Then you should consider buying a discount multi-pack of exam vouchers from Microsoft – the "Microsoft Certification Exam Pack" from Prometric. If you’re only going to sit one exam, you can pay 15% on top of the usual exam price and have a second shot at the exam – should you need it – for free. If you’re sitting exams as part of a course at a training partner testing centre, then it is likely they will have second shot vouchers ready for you as part of the deal.
The 70-668 has been out a month, and I’ve only just got round to taking it. When I sat the 70-667 beta, Microsoft gave me the MCITP Administrator certification as well by mistake… A bit of googling showed me that this was a known bug in their certification database and they’d taking it away again by 1st of September from any MCPs who hadn’t really sat 70-668.
