I've finally decided to pursue the 2012 track, and hope to complete MCSE within the next few months. I have several years of work experience with 2012/2012R2, and have been using these versions of Windows Server since they were pretty much released. Being fortunate enough to work in a complex environment with several Microsoft and 3rd party services and management tools running along side the OS, I get to acquire a lot of knowledge through experience. But to pass these exams, you have to study as well. So I used three different books while studying for 410 (fortunately I like to read), the official Traning Guide and Exam ref by MS, and the Mastering 2012R2 book by Sybex. Of those three books, I would recommend the Exam ref and Mastering 2012R2, the official traning guide wasn't too impressive.
I had a wide range of questions on the exam, which pretty much touched upon every objective of the exam. I did best in the Hyper-V section. Now, onwards to 411.
Btw, I have shared some of my notes on my blog, so if you are interested, do check them out.

I'll try to add more notes if and when time permits.
