Questions on this idea a shift, by year

2017–2026. Asked in 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.

How JEE Main framed it

Numerical value is the usual form. Skill tested: multi-step.

  • Cation group identification then oxidation state
  • Identify complex from cation test then magnetic moment
