The shift-wise JEE Main 2025 marks vs percentile analysis for the January session is now available. Percentile trends varied across shifts due to differences in paper difficulty and normalization. The data helps candidates estimate performance and understand scoring patterns before results.

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.

Percentile	Shift 1 (Morning)	Shift 2 (Evening)
99	158	186
98	133	163
95	101	129
90	74	98

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.

Percentile	Shift 1	Shift 2
99	178	188
98	154	165
95	120	132
90	89	101

JEE Main 2025 January 24 Shift-Wise Marks vs Percentile

The January 24 exam was moderate to slightly tough, with longer calculations in Mathematics.

Percentile	Shift 1	Shift 2
99	183	200
98	158	177
95	121	142
90	85	112

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.

Percentile	Shift 1	Shift 2
99	148	170
98	126	149
95	96	118
90	70	90

JEE Main 2025 January 29 Shift-Wise Marks vs Percentile

Both shifts on January 29 were relatively balanced with consistent scoring trends.

Percentile	Shift 1	Shift 2
99	174	176
98	153	154
95	123	127
90	94	101

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.
