@Pra4surf1 I'm really sorry to hear about your test and the venue loosing power. It can be really devastating to work so hard towards a date and then have something random happen and not be able to even finish the exam.
I wanted to let you know that I am very familiar with your current position. I started studying for the exam in January 2020. I finally passed in June 2022. I studied for the entire 2.5 years. The only time I took off was the time between the paper test and getting the results. I took the paper test 3 times and the CBT once. I was devastated that I did not pass on the last paper exam because I didn't know how I could pass the test without references.
On my final attempt (CBT exam) I felt completely trashed and burned out. I thought the morning went well, but I had to take the whole 4 hrs. In the afternoon I was angry. So angry. The questions were outside of everything that I had studied for the last 2 years. I had never seen the types of questions that were asked. I knew I failed and I honestly did not think that I had it in me to try again. Things were already so bad for me that I actually started to see a therapist as I was preparing for my 4th attempt. I'll share with you something that my therapist said that really helped me: You have to treat every failed attempt as a loss and allow yourself to grieve. And burnout is ABSOLUETLY real. I thought she was crazy, but as soon as I started to cut myself some slack and really allowed myself to grieve and relax it really helped me manage my emotional and mental health going into my 4th attempt. For a long time I felt ridiculous about the fact that this stupid test lead me to a therapist. But 2.5 yrs is a lot of effort and sacrifice. That breaks people. So cut yourself some slack.
Here are some facts: This test is very hard. Don't beat yourself up about it. There is absolutely no way you can know every single thing that these topics cover. A lot of us are working full time jobs and have kids and families to take care of, acknowledge the fact that we are all stretched thin.
When it comes to passing this test, I feel it is 40% luck(problem selection and lucky guesses) and 60% knowledge. Don't give up. Take some time off, relax, give yourself a physical and mental break, see a therapist if you need to but don't give up.
