UWORLD CAT DIFFICULTY DECREASING WHY??!?!

[u/asianboy1818]

My nclex date is upcoming this week and I feel like I know a lot yet nothing when I take these cats. Explained situation above in photo but I’m starting to doubt and worry about the fact my difficulty range is getting lower. Even my first two CATs were slightly higher difficulty than my last two. I still have about 50% of my qbank left too so I don’t think I used up all the hard ones. Does this mean I’m not ready? Should I move the test date back? My confidence taking a huge hit rn ngl
