Extremely Slow and lagging experience

Hi, I have seen a lot of post on this forum about the entire PSSI browser and the session to be lagging and slow
This happened to me recently when I tried to give my attempt on CKAD. I had covered all the topics in my practice sessions mastering the time factor including killer.sh. But when you come to the actual exam overall experience being so slow and ancient half of the time goes in anticipating what will be the next question and also be quick enough to finish the exam in 120 minutes so even if I knew all the questions and I could attempt all of them I was still behind, and my overall anxiety was built up that led me a score of just 55% at the end.
This is really sad that even after working in Kubernetes environment at work and also knowing the concepts, you do not get that agility in the real exam to pass a certification and the entire linux terminal and the session is quite cumbersome. I have also opened a ticket to them, and at the same time I am reading post on Reddit as well that this is for everyone who have kind of gotten a similar experience and failed. I wonder how others pass this exam and post about it, but I have seen majorly others going through this more often.
