MD-102 Practice Test Does Not Prepare You for the Actual Exam + Poor Support Links

My point here is that literally no person is going through the practice assessment unless they are planning to take the exam.

Completing the practice assessment does not, in any way, "assess your readiness, determine where additional preparation is needed"; because you can do very well on the practice assessment and still FAIL the exam. Which specifically shows that the Practice Assessment did NOT "assess your readiness, determine where additional preparation is needed". 
On the https://learn.microsoft.com/en-us/credentials/certifications/modern-desktop/?practice-assessment-type=certification page where it discusses the Practice Assessment it says

"Practice assessments provide you with an overview of the style, wording, and difficulty of the questions you're likely to experience on the exam. Through these assessments, you're able to assess your readiness, determine where additional preparation is needed, and fill knowledge gaps bringing you one step closer to the likelihood of passing your exam."

I'm saying that statement is false. That statement also contradicts the statement you quoted in your reply to me.

These questions are not the same as what you will see on the exam nor is this document illustrative of the length of the exam or its complexity (e.g., you may see additional question types, multiple case studies, and possibly labs). These questions are examples only to provide insight into what to expect on the exam and help you determine if additional preparation is required.

The Practice Assessment is not

• the style
  • no case studies
  • not the same style
  • no build/reorder lists
  • no active screens
  • no “hot areas”
  • no exhibits (single or multiple)
  • no questions about code/script entry
• the difficulty
  • The questions on the Practice Assessment are simplistic compared to the exam.

The exam demo does show what those type of questions look like but they are fake questions that do nothing in preparing a learner for the exam.

The link you provided for  https://learn.microsoft.com/en-us/credentials/support/exam-item-challenge-process is not on the Practice Assessment pages, or the results pages or the training pages and is, therefore, hidden unless you know where to look. It should be much more accessible.

Lastly, you directed users to MeasureUp (which when I try to reply here with a link like you put I get an alert pop up that says we are not even allowed to mention Measureup in this Community.

If I go pay a third party for their exam prep, are they going to have questions that more closely match the exam? If they do, why would Microsoft not? If they don’t, what would be the point?
