NBME 25- Need advice

Hey guys, just wanted to get some opinions. My Step 1 exam is in about 2 months, and l've been giving offline NBMEs to check my baseline before switching to the online ones. NBME 20 (Oct 22): 80/200 - 40% NBME 21 (Oct 27): 102/200 → 51% NBME 25 (Nov 1): 120/200 →60%

I told myself that once I cross 60% on the offline ones, I'll move to the online NBMEs. Now that I finally hit that mark with NBME 25, I'm a bit confused. NBME 25 honestly felt way easier than 20 or 21. I also noticed some overlap. Like similar question concepts, maybe even 2-3 repeated ones. I had reviewed my 20 and 21 thoroughly, so maybe that helped. I did make around 7-8 silly mistakes, but overall it felt more straightforward.

So now I'm wondering, -Was NBME 25 actually easier for others too? -Or are my marks just falsely inflated because I'd already seen similar concepts from earlier NBMEs? -Or did I actually improve?

Would really appreciate if someone could clear this up for me. Thank you so much!
