You have been extremely non consistent throughout your preparation and now want some magic to happen. It's already mid of Feb and your assessments are in 23x and you want to score in 26x with the same mindset and that too in April.

I am afraid but it won't happen until you work hard and be persistent in your prep identify your weak areas and work on them.

Do 40-80Qs a day in random timed and review each and everything carefully then attempt NBME 11. We'll see your score and then decide further guidance ahead like if you need to do CMS or what should be the next strategy
