What moves on the Probit & Logit Models diagram
Lowering the midpoint shifts the whole S-curve left, raising success probability everywhere, with the largest gains where the curve is steepest.
Success probabilities follow the S-curve of the underlying score.
Free prep courses roll out to every candidate.
The S-curve slides left: any given score now carries a higher chance of success.
The biggest winners are again mid-range candidates, where the curve is steep. Marginal effects live in the middle of an S.
Examiners ask this as: prep course, coaching, easier outcome, training program, widespread tutoring.
