The shift-wise JEE Main 2025 marks vs percentile analysis for the January session highlights how paper difficulty and normalization impacted scores across different exam dates. Understanding these trends can help candidates appearing for JEE Main 2026 Session 1 estimate their performance and set realistic percentile expectations.
The shift-wise JEE Main 2025 marks vs percentile analysis provides crucial insights into how variation in paper difficulty across different shifts influenced candidate scores during the January session (January 22 to January 29, 2025). This analysis also serves as a reference point for aspirants preparing for JEE Main 2026 Session 1, helping them understand expected scoring trends. The National Testing Agency (NTA) conducts JEE Main in multiple shifts and applies a normalization process to ensure fairness when question paper difficulty varies across sessions.
Why Shift-Wise Marks vs Percentile Varies in JEE Main?
The relationship between marks and percentile in JEE Main is not fixed and depends on several factors:
- Variation in difficulty level between shifts
- Number of candidates appearing in each shift
- Relative performance of candidates within a shift
Due to normalization, the same raw score can result in different percentiles across shifts. For example, scoring 180 marks in a tougher shift may fetch a higher percentile than the same score in an easier shift.
JEE Main January 2025: Toughest and Easiest Shifts
Toughest Shifts
Shifts with lengthy Mathematics, complex Physics conceptual questions, and multi-step numericals were rated toughest. In such shifts, candidates achieved higher percentiles at comparatively lower marks.
Easiest Shifts
Shifts dominated by direct Chemistry questions and formula-based Physics were considered easier. In these shifts, marks required for top percentiles, such as 99 percentile, were noticeably higher.
