Hi Arko. I actually took the exam the other day and passed with a fairly good score - 847. My initial gripe with these practise tests, based on my own experience, was somewhat unfounded. The questions in the real exam were fairly similar in format and complexity.
The only criticisms I still hold is the length of the these tests, trying to rush a test isn’t helpful, and that in the exam you can’t move forward and backwards between questions as much as is practise tests, so they seem a little easier than the exam would actually be. But I suppose you can discipline yourself not to move back and forwards between questions and press the pause button to give yourself more time to make it more realistic.
Of course, the key to these tests is understanding the type of questions that may be asked and reading the relevant Azure Docs content to it. Configuring it on ARM is also helpful.
So, for the price, I think these tests are pretty good. They won’t help pass the exam on their own, but certainly help you prepare for the exam by suggesting what to study.
Good luck if you attempt the exam again.
