I am glad I have come across this post. I am currently studying for my MS900 exam. The questions that I am receiving in the practice tests are of much higher/complex/standard than what I have studied for.
Where you stated, "It gets quite confusing as you don't know if you are well prepared for the exam or not. Would really appreciate an answer!" resonates with me a lot.
Will the MS900 exam have questions of this complexity?
