JEE Main

What it is

JEE Main is a computer-based test held twice a year by NTA. It does two jobs at once: it admits students to the NITs, IIITs and other government-funded colleges, and it decides who qualifies to attempt JEE Advanced for the IITs. Whichever of your two session scores is higher is the one used for ranking.

Who can apply
  • Passed Class 12 in 2024 or 2025, or appearing in 2026
  • Subjects: Physics & Maths, plus one of Chemistry / Biology / Biotech / Vocational
  • For NIT/IIIT/GFTI admission: 75% in Class 12 (65% for SC/ST/PwD) or top-20 percentile of your board
  • No age limit; you may appear in both sessions, across two consecutive years

Why it’s different & what to watch
What makes it special
  • Two shots a year — only your higher NTA score counts.
  • It’s a percentile, not a percentage: ‘99 percentile’ means you beat 99% of test-takers.
  • One exam, two doors: it feeds NIT/IIIT counselling and decides who sits JEE Advanced.
Common mistakes
  • Skipping Session 2 after a ‘good enough’ Session 1.
  • Reading percentile as if it were a percentage of marks.
  • Neglecting Class 11 — it’s nearly half the paper.

What makes it special
  • No direct entry — you must clear JEE Main first.
  • Only 2 attempts, and they must be back-to-back years.
  • Both papers in one 6-hour day; skip either and you’re out.
  • There’s a per-subject minimum cutoff — you can’t pile all your marks into one subject.
Common mistakes
  • Over-attempting multiple-correct questions and losing negative marks.
  • Practising only Paper-1-style questions.
  • Assuming the Advanced syllabus is just ‘Main + a bit more’.

  • No negative marking — it’s a pure scoring game, so attempt everything.
  • Two attempts; the better percentile is used and Session 2 is optional.
  • Scores are normalised to percentile across shifts, so a ‘tough’ slot won’t hurt you.
Common mistakes
  • Leaving questions blank — that’s free marks lost.
  • Studying only NCERT when the Maharashtra board syllabus differs.
  • Under-preparing Maths, the highest-weight subject.

Common mistakes

  • Believing a JEE Advanced rank still gets you into IISERs — it doesn’t anymore.
