The shift-wise analysis of JEE Main 2025 marks vs percentile for the January session provides insight into how exam difficulty influenced scores across different dates and shifts. Since the National Testing Agency conducts the exam in multiple shifts, a normalization process is applied to ensure fairness among candidates. This analysis helps aspirants understand expected percentiles based on raw scores and serves as a reference point for candidates appearing in upcoming JEE Main sessions.
How Shift Difficulty Affects JEE Main Percentile?
JEE Main question papers vary slightly in difficulty across shifts. As a result, the same score may fetch different percentiles depending on how challenging a particular shift was. Key factors influencing marks vs percentile include:
- Variation in Physics, Chemistry, and Mathematics difficulty
- Number of candidates appearing in each shift
- NTA’s normalization formula to balance score disparities
Typically, tougher shifts allow candidates to secure higher percentiles with relatively lower marks.
JEE Main 2025 Toughest and Easiest Shifts in January
Based on student feedback and paper analysis, some shifts were more demanding than others.
- Tougher shifts generally featured lengthy Mathematics sections or concept-heavy Physics questions
- Easier shifts were characterised by NCERT-based Chemistry and formula-driven Physics
In easier shifts, higher marks were required to achieve top percentiles such as 99.
JEE Main 2025 January 22 Shift-Wise Marks vs Percentile
The January 22 papers showed moderate difficulty overall, with the evening shift being slightly tougher.
JEE Main 2025 January 23 Shift-Wise Marks vs Percentile
Both shifts on January 23 were balanced, though Mathematics was time-consuming in the evening shift.
JEE Main 2025 January 24 Shift-Wise Marks vs Percentile
The January 24 exam was moderate to slightly tough, with longer calculations in Mathematics.
JEE Main 2025 January 28 Shift-Wise Marks vs Percentile
January 28 is considered the toughest exam day of the session, particularly the evening shift.
JEE Main 2025 January 29 Shift-Wise Marks vs Percentile
Both shifts on January 29 were relatively balanced with consistent scoring trends.
What Candidates Should Note?
The marks vs percentile figures are indicative and based on difficulty-level analysis. Final percentiles may vary after normalization and result declaration. Candidates are advised to use this data only for performance estimation and rely on official NTA results for confirmed scores and rankings.
