I sat the M255 exam today, no problem with the material, although I almost ran out of time, because I was trying to ensure my writing was legible, and I was pretty slow because of that.
I'm hoping that I've scored enough to get a distinction but I can't be sure, 15 points can be lost pretty easily, and of course, I remembered something I missed a couple of hours after finishing. I'll just have to wait until December to find out.
Another model complete though.
