Reviews
Mar 2021
It's quite challenging given the time frame provided, but I think that's how the certs should be. One has to prepare really hard, especially people from non-tech backgrounds like Project Management etc.

The hands-on approach with real examples is definitely superior to "normal" exams. Was an overall pleasant experience, which reduced the stress levels after reading the requirements and getting the "hands dirty".

Interface was better than any practice test I have taken. The instructions for the problems were quite clear, for the most part.

Way of conducting the exam especially during this pandemic time is really appreciated.

Hands on tests, things can be done multiple ways, and this exam allows for that.
