Dissapointed with nbme 11 score

I just got my NBME 11 score: 252, and honestly I'm feeling really disappointed. My target is 260+, so seeing my score stay around the same has been discouraging.
My NBME scores so far:
NBME 9: 236
NBME 10: 254
NBME 11: 252
I don't know what to do from here.
For those of you who managed to jump from the low/mid-250s to 260+, what helped you the most?
Is it enough to carefully review and learn from the NBMEs I take, or should I be doing more
I'd really appreciate any advice from people who have been in a similar situation. Thank you!
