Hello,
I agree with Kyle that your scores look good for your practice exams but only you can know your own confidence level for being ready for the real thing.
My strategy while taking the exam was first to remain calm and breathe. That really was the most important thing that I felt got me through it. I made sure I had a good breakfast that morning, didn’t look at any exam material and listened to relaxing music. For each question I first tried to recognize what process group and knowledge area it was referencing and then narrowed down the answers until I could pick the best answer. If I didn’t know a question, I wouldn’t let myself panic but kept reminding myself (in my head) that I was prepared and was in control.
I hope that helps!
