Whoa! My first real exam since university seven years ago!
I passed 070-316 (Developing & Implementing Windows based Applications with C#.NET) yesterday with ease, which was a relief.
The transcendor exams were really helpful, and actually I found the real exam much easier. (Some of the Transcendor questions are in fact ambiguous, with the answer being more of an opinion than of a fact)
What helped my nerves was having a parachute from Microsoft with their 'Second Shot' promotion: http://www.microsoft.com/learning/mcp/offers/2ndshot/
On to the next exam! Web Services (070-315)
