My wife was preparing for PL-300 exam, this would have her first Microsoft certification. But experience was totally ruined by Pearson Vue and their proctors.
There software just doesn't work when you need it, I tried it on 3 different laptops.
Initially during the testing software checked the required services on laptop and gave it a go, while checking in for exam software stopped responding and didn't launch after multiple attempts.
We tried it on second laptop, this time software launched, again tested the system and placed us in the queue. But as soon as proctor joined, software stopped detecting camera, and even after multiple restart camera was not detected.
This process already took 45 mins, tried it again on a different laptop. Software kept hinting to exit out of teams, outlook, skype, Firefox, and every other software. However none of these softwere actually running, they were all closed from task manager.
We ended up uninstalling outlook teams and every O365 apps. And finally launched the exam on third machine, this time proctor couldn't see the screen and was highly rude.
I don't think Pearson Vue and their proctors do take these certificate exam seriously, quality of their software and proctors has just been degrading.
