Any example of how does the certification exam looks like?

Hi!
I recently discovered that Unity is going to arrange a certification event next week near my city. I'm thinking about getting certified but I'm not even sure how does this exam work...

I have been working with Unity for the last three years but I'm afraid I'm not prepared in some areas just because I have not worked on them for ages... I work with NGUI and I have never worked with the new built-in UI, I only know the old UI system. I have the same issue with mecanim, 3D ( I have been doing 2D stuff for over a year), lightmapping...

I'm a programmer but I can see coding related topics are not widely covered in this exam... So that's why I don´t know it's worth taking this exam, even more considering I'm working and I can't dedicate full time this remaining week.

Is there any certification example available so I can evaluate if I have any chance to pass the exam? Any resource available would be very welcome.

Thanks in advance!
