Feeling unprepared for my NCLEX next week!

I'm scheduled to take my NCLEX RN towards the end of next week and I have never felt so panicked in my life. I've been studying since I graduated in May, but I feel lost at the same time. I'm unsure if I've been preparing correctly and as my testing date gets closer I get more and more nervous. I have an ICU RN position set up for me that I start in July that obviously requires me to pass my boards, so I NEED to pass or I lose my dream job.

I did fairly decent throughout nursing school, with mostly B's in each class. My school's program has prided itself on how well their students do on the NCLEX, with 97% of graduates passing it the first time. My program also focused heavily on ATI, which I usually scored 2-3 on, and the comprehensive predictor I took in my last semester of school gave me a 99% chance of passing the first time.

Now, despite this I didn't want to slack on my studies for the NCLEX. I've been reviewing around a chapter a day, and doing 75-200 practice NCLEX questions a day for about a month (using mostly Saunders and the NCLEX-RN Mastery app). Still, I feel unprepared and at this point I feel like none of the knowledge is sticking.

Any advice before the test? And extra study tips? Anything would be much appreciated!
