However, if you have lots of work experience with Server 2012 or have previous certifications with Microsoft, I can imagine that this may be doable. Which test is harder? That is a tough question because each person has different passions and ambitions. I have heard from some the 410 was the hardest, others say the 411, I found the 412 to be the hardest. I think the 410 is the most straight forward as far as material goes but it is also your introduction to how Microsoft does things so that is always a challenge. The 411 covers some outdated technologies that I found to be almost a waste of time. The 412 covers a whole lot of different, and complicated, technologies which made it hard to focus study on any core area. Don't get me wrong, passing one test a month (or a test every few weeks) is possible but it is a lot of work and something that a lot of people aren't equipped to do. Make sure you include lab time in your studies. That helped me more than anything else.

I believe I spent a month studying before my first attempt and then another week prepping for my second attempt. The exam topics themselves aren't difficult, but you need to know how they work, how to configure them, and how to troubleshoot.
