I'm currently studying for the 70-461 - Querying SQL Server 2012 exam because the company I just started at needs to have us certified to retain their Microsoft Silver Certified Partner designation. Its kind of a "foot in the door" thing, to impress new customers, but its also about getting the SQL Server software cheaper.

However, I fully intend to get all three of the certifications eventually, on my own, regardless of it being required or not. I haven't done a lot of Reporting Services and BI work so studying for that exam will be a real challenge, which to me is the whole point. If you're not challenging yourself every day then you're going to stagnate. You also need to keep up to date with each new version. The exam itself is not the goal, but it is a good, objective measurement of where you're at.

And if you're half as good as you think you are, you shouldn't need to even study for it, just go ahead and write the exam. What are you afraid of? 😛
