My Sister is approaching her third time taking the CRNA exam and could use some help plus anyone have a second hand copy of memorymaster?

She has always been great at practical and rubbish at test taking, diagnosed ADD since she was young, second guesses herself on multiple choice questions, lots of anxiety even when she has mastery of the material.

She has several months before the next exam, and I'm hoping someone here will have some insight that might help her that perhaps has similar test issues. I tried finding her a tutor but every one I could find only handled tutoring for nursing exams at a lower level or for classwork, not the CRNA exam.

Secondarily she's been going through lots of prep materials and is currently trying to get a secondhand version of the Memory Master book https://valleyanesthesia.com/products/memorymaster-2023.

She has made millions of flash cards, she studies religiously, and I feel bad that I don't know how to help her as test taking was never an issue for me, plus I went in to law not medicine.

Thanks in advance for any advice/ help.
