Why most candidates plateau

Since Step 1 moved to Pass/Fail in 2022, the failure rate for IMGs climbed and study strategy got messier. Candidates still drill every organ system uniformly when one or two are doing all the damage, and NBME forms 29 to 31 are too expensive to burn through on exploration.
