-
Also serves as a qualifying exam for JEE Advanced (top 2.5 lakh rankers eligible).
✅ Exam Pattern:
-
Subjects: Physics, Chemistry, Mathematics
-
Mode: Computer-Based Test (CBT)
-
Duration: 3 hours
-
Total Marks: 300
-
Attempts per year: 2 (January & April sessions)
-
Eligibility: 12th pass (or appearing), no age limit (as per NTA)
🔷 JEE Advanced
✅ What it is:

-
Age and academic criteria apply (usually below 25 years, 12th pass within 2 years).
✅ Exam Pattern:
-
Papers: 2 (Paper 1 & Paper 2) — both mandatory
-
Subjects: Physics, Chemistry, Mathematics
-
Mode: CBT
-
Duration: 3 hours each (total 6 hours)
-
No fixed pattern – changes every year (includes MCQs, numerical, and match-the-following)
🎯 Key Differences:
| Feature | JEE Main | JEE Advanced |
|---|---|---|
| Level | Screening/eligibility | Final selection for IITs |
| Conducting Body | NTA | One of the IITs |
| Colleges Covered | NITs, IIITs, GFTIs, others | IITs, IISc, few others |
| Attempts/Year | 2 sessions (Jan, Apr) | Once a year |
| Question Type | Fixed pattern (MCQs + numericals) | Varies every year |
