Advice midway through NBMEs

20 days out. Stats so far-

NBME 9- 73% (241)
NBME 10- 76% (246)
NBME 11- 80.5 (252)
Free 120 (2021)- 80%
NBME 12- 75.5% (248)- Gave this today, felt really weird

I am targeting a 260+, Do the newer NBMEs feel easier? What can i do to push beyond. Anyone who has been in the same situation but pushed beyond 260 on the real deal, thanks!
