Why did CSE 2024 Prelims cutoff bounce back to 87.98 from 2023's 75.41?

The 12-mark recovery happened because two of the three 2023 drivers reversed: GS-I shifted to a conceptually structured 'moderate-to-difficult' design rewarding reasoning over rote, and CSAT stayed tough but stopped its outlier brutality. Vacancies remained near identical (1,056 vs 1,105), so the difference was almost entirely paper-design.
