Sit an exam and take a second shot at it for free
We've just announced the second shot promotion - this was run a while ago (about 18months) with great success.
The deal is that if you purchase a Microsoft Exam between now and June 30 and you fail,you'll get a second shot at the exam for free.
So get busy - there are no more excuses :-). I might even have to sit some ASP.Net exams...
