It's extremely frustrating dealing Pearson Vue software to take the Microsoft certification. Udacity is so much simpler.
I try taking the certification twice and both time I got flag by the system. I have a MacBook since I do web development. The first time the webcam screen was just blank. It voided my voucher. I had to wait a month to get another voucher code. Secondly, the system never opens the test, it just froze on a blank screen. I open an app to kill the process and it voided my exam again.
I recommend having a coding bootcamp come up with better software as a project and then hire those guy :)
