Does a second pass help?
Among students with the same first-pass accuracy, those who did a second pass scored +5.4 points higher when the first pass landed at 55–64%, +4.2 at 65–74%, and +2.5 at 75%+ (312 second-pass reports). All three comparisons are positive, including the 75%+ band, so they do not support a sharp first-pass cutoff. Students chose their own study plans, so this does not prove that a second pass caused the higher scores. Practice exams remain more informative for tracking readiness than question count alone.
