Questions on this idea a shift, by year
2017–2026. Asked in 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
Raw count: 2017: 0 in 1 shift · 2020: 0 in 12 shifts · 2021: 0 in 24 shifts · 2022: 0 in 24 shifts · 2023: 0 in 12 shifts · 2024: 1 in 18 shifts · 2025: 1 in 8 shifts · 2026: 0 in 9 shifts.

How JEE Main framed it
Numerical value is the usual form. Skill tested: calculation.
- Time for zero order change from half-life
- Sum from rate law and graph order
