    Love this. I am about to start studying for this exam. Do you have any update on study material?


    1. Chris Pietschmann July 25, 2017 at 5:35 pm

      No, I don’t have any update on study materials. This exam is really new still.


  2. Hi , How do you guys study without material ?


    1. Chris Pietschmann October 16, 2017 at 7:46 pm

      Mostly documentation and through trial and error playing with the tools. It can be very time consuming at times. Oh the difficulty we go through to create training material some times. 🙂


      1. I’m actually fond of R and using it since a while for data visualization . Can you tell me which type of documentation you have , I need a starting point and need to make sure I’m preparing for the exam and not for the entire tool

  3. Hi Chris , could you please let me know if there are a good source for these documentation ?

    Thanks in advance!!!

      There’s not an Exam Ref book for 70-773 from Microsoft Press yet. Microsoft documentation has a lot of resources, and then there’s also the mediums you mention. You could also look into on-demand video services like or as well.

      There aren’t any exam ref books for the 70-773 certification exam. Also, I don’t anticipate any getting published since this exam is being retired June 2019.
