Usually speakers take offence if you wear headphones in their talk. For the exam cram session it was a requirement. This was because it was a cubical walled room with an open top next to a study hall.
While no-one was going to come out of this session ready to take a test, I am glad that I took the time to attend it. There was a fair amount of material that you should know already if you have ever taken a certification test before. This was packed around a mix of key concepts and some tidbits that marked where some of the pitfalls are for this particular test. The biggest warning was that the test is based on Windows Phone 7.0 and not Mango meaning that you have to be careful that you don’t answer a question in the wrong context.
I would suggest if you have a chance to take attend a free session grab it. It is a good break from the other hard core talks and will get your mind into a mode for getting your next certification. Good luck.
