Today I finsished taking the two Data Vizualization BETA exams. Together these two exams will earn an MCSA on Business Intelligence Reporting. I can see a high demand for teaching these two courses. Definitely an area that not many people currently teach as PowerBI is only two years old. It will be interesting to see how well I did. If you watch the corresponding edx.org courses, you should do fine. Compared to other MCP exams, these are very straight forward. My one tip is to study DAX functions.
