JEE Main 2026 (23 Jan, Shift 1) paper analysis

JEE Main 2026 (23 Jan, Shift 1) was moderately tough compared with all 163 JEE Main papers since 2019, and the 4th easiest of the 10 shifts of the January 2026 session, by our question ratings.

Difficulty by subject

  • Physics: Moderately easy
  • Chemistry: Moderately tough
  • Mathematics: Moderately tough

Difficulty is Autonise's own rating, not NTA's. Every question in our bank has a difficulty rating. We work out the marks a well-prepared student would expect in every JEE Main paper and rank this shift against all of them: the easiest fifth is "Easy", the toughest fifth "Tough". NTA works percentiles out within each shift, so the same marks give a higher percentile in a tougher shift; the percentile predictor uses this level.
