ASCP worries/anxiety

I have about t-1 week until my exam. I have been using 2 main things to study, which has been the MediaLab LabCE for practice exams, and the book “The Bottom Line Approach”. I’m doing okay on selected area tests of specific subjects, but when it comes to my 100 question adaptive practice exams, I can’t get past a difficultly of 5.17 and it is making me nervous. I just wanted to ask if anyone has any tips to help me improve difficulty/score on the practice adaptive tests, and well as any reassuring words/advice anyone has. It will all be appreciated <3
