70-773 Exam Questions Answered: Microsoft Candidates' FAQ
Microsoft Analyzing Big Data with Microsoft R is an official exam run by Microsoft under exam code 70-773. Passing it awards the MCSA: Machine Learning certification, which sits at the Professional tier. It also counts toward related credentials such as MCSA: Machine Learning, Microsoft Certified Professional. Certified professionals remain in shorter supply than the market wants, which is precisely why this exam keeps showing up in conversations about better roles and better pay.
The Microsoft Analyzing Big Data with Microsoft R exam gives you 150–180 to work through 40–60 questions. That is a tight ratio, and it punishes candidates who get emotionally attached to any single item. The fix is mechanical: answer what you know, flag what you do not, and keep moving. A few full-length timed runs in the Actual4Exams test engine, with its randomized question order, will calibrate your pace far better than untimed reading ever could.
The official fee for Microsoft Analyzing Big Data with Microsoft R is 165 USD, and 700 out of 1000 is what passing takes. The uncomfortable part: retakes cost the full 165 USD again, which makes preparation the cheapest line item in this whole project. Before booking, put yourself through repeated scored sessions with the Actual4Exams practice tests and compare results over time; a stable margin above the passing line, not a single lucky run, is when you are ready.
