ICE Table Construction

JEE Main asked ICE Table Construction 4 times in 4 of the 108 shifts Lumi analysed, in 2021, 2022 and 2023. It belongs to Chemical Equilibrium, in Equilibrium (Chemistry). The longest wait between two years asking it was 1 year. In 2021 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2022 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
