Everything worked as expected. Also, free practice exams on killer.sh were a HUGE help.

The overall experience was very good , The prerequisite task by proctor was very smooth. The exam questions were very clear, and UI is friendly and easy to navigate.

It's been a few months since my last attempt, the interface is a whole lot better, and the clusters are more responsive.
May 2021
The exam is well balanced, and it is easy to switch between questions. What really stands out is a provided weight for each one, summing up to 100%, great transparency.
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.
Feb 2021
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".
Jan 2021
Interface was better than any practice test I have taken. The instructions for the problems were quite clear, for the most part.

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