Just a quick discussion to see whether you are intending to study and sit for one of the Microsoft SharePoint 2013 exams ?
If so, when and how are you intending to learn ?
If you’re using 2010, then doing the 2010 exams may still be worth the effort. In the long term, doinmg the 2013 exams is of course advisable, though there isn’t too much content available yet, as the dev exams aren’t officially out yet (there’s more content for the IT Pro exams, as you can already take them)
