I successfully passed first Microsoft exam in 6 years. After AX University boot-camp in Zagreb I completed MB6-513 Microsoft Dynamics AX 4.0 MorphX Solution Development so I have a title Microsoft Certified Business Management Solutions Specialist / Microsoft Dynamics AX 4.0.
I'm sure I can't disclose information about the exam publicly, so if you have any questions or you would like some tips, contact me.
PS: Don't worry, I'm not switching camps and going from .NET to Dynamics. It's just a detour.
