Shift-Wise JEE Main 2025 Marks vs Percentile

The marks vs percentile JEE Mains 2025 shift wise relationship is dynamic because of the variation in question papers. Normalization is applied to scale the scores of candidates across multiple shifts to a single platform.

• Difficulty Variation: Each shift has a unique set of questions, leading to different difficulty levels.

• Normalization Logic: Because of these variations, the same marks may not result in the same percentile across different shifts. For instance, a score of 180 might fetch a higher percentile in a "Tough" shift compared to an "Easy" shift.

JEE Main January Session 2025: Toughest and Easiest Shift

Identifying the toughest shift of JEE Mains 2025 and the easiest shift of JEE Mains 2025 is a key part of post-exam analysis.

Toughest Shift: Typically, shifts with high-difficulty Mathematics or complex Physics conceptual questions are categorized as tough. Candidates in these shifts often achieve a higher percentile with lower raw marks.

Easiest Shift: Shifts where Chemistry is direct and Physics is formula-based are often perceived as easier. In these sessions, the jee 2025 marks vs percentile requirement for the 99th percentile tends to be significantly higher.

Shift-Wise JEE Main 2025 Marks vs Percentile  

The following sections provide a detailed breakdown of the JEE Mains 2025 shift wise marks vs percentile based on the difficulty levels of each specific date.

JEE Mains 2025 Session 1 January 22 Shift 1 & 2 Marks vs Percentile

On 22 January, the morning shift (S1) had moderate difficulty, with Chemistry scoring well but Mathematics slightly time-consuming. The evening shift (S2) was a bit tougher, especially in Maths, leading to slightly lower marks for the same percentile compared to S1. 

JEE Mains 2025 Session 1 January 23 Shift 1 & 2 Marks vs Percentile

The 23 January shifts were balanced overall. Morning shift (S1) emphasized formula-based Physics and NCERT Chemistry, while Mathematics was lengthy. Evening shift (S2) saw more challenging Maths, which slightly lowered marks required for top percentiles. Chemistry again remained the most scoring section for both shifts.

JEE Mains 2025 Session 1 January 24 Shift 1 & 2 Marks vs Percentile

On 24 January, both shifts were moderate to slightly tough. Morning shift focused on NCERT Chemistry and formula-based Physics, whereas Evening shift (S2) saw more scoring Chemistry but lengthy Maths questions. Students with quick calculation skills benefited in S2.

JEE Mains 2025 Session 1 January 28 Shift 1 & 2 Marks vs Percentile

The 28 January shifts were the toughest of the January session. Morning shift (S1) saw moderate difficulty with slightly lower scoring trends, while Evening shift (S2) had lengthier Maths and Physics questions, causing marks for top percentiles to drop. Chemistry remained relatively scoring.

JEE Mains 2025 Session 1 January 29 Shift 1 & 2 Marks vs Percentile

On 29 January, both shifts were moderate and relatively balanced. Morning shift (S1) had formula-heavy Physics and NCERT Chemistry, while Evening shift (S2) was slightly easier in Maths but consistent with scoring Chemistry. Top percentile marks were similar across both shifts.
