JEE 2027 FAQ: 35 most-asked questions

JEE Main is conducted by the NTA and is the gateway to NITs, IIITs and GFTIs (via JoSAA). JEE Advanced is conducted by a zonal IIT and is the gateway to the 23 IITs. You must clear JEE Main and be among the top qualifiers to be eligible for JEE Advanced.

Paper 1 (B.E./B.Tech) has Physics, Chemistry and Maths - 25 questions per subject (20 MCQs and 5 numerical), 75 questions for 300 marks in 3 hours, with +4 for a correct answer and -1 for a wrong one.

JEE Main 2027 is expected to be held in two sessions, roughly January and April 2027. You can appear in one or both; if you sit both, the better NTA percentile is used.

JEE Advanced has two compulsory papers, Paper 1 and Paper 2, both held on the same day (expected late May 2027). The pattern and marking scheme vary every year and are decided by the organising IIT.

JEE Main has -1 for wrong MCQ answers and no negative marking for numerical-value questions. JEE Advanced uses a variable marking scheme that changes each year - read the instructions carefully on exam day.

Yes, this is the standard route for NIT, IIIT and GFTI aspirants. JEE Main is a standalone exam and your Main score and All India Rank are enough to participate in JoSAA counselling for NITs, IIITs and the Government-Funded Technical Institutes (GFTIs). JEE Advanced is only needed if you want an IIT B.Tech seat. Some state and private deemed universities also accept JEE Main scores. So an aspirant whose target list does not include the IITs can prepare for and write JEE Main alone, skip Advanced, and still get into a strong engineering institute through the same JoSAA counselling cycle.

Different, not strictly harder. JEE Main is fixed-pattern with single-correct MCQs and numerical questions, +4/-1 marking, and a focus on speed and accuracy across 75 questions. JEE Advanced changes its pattern every year, mixes MSQs (multiple-correct with partial credit), paragraph blocks, match-the-column and integer-type questions, and tests deeper multi-concept reasoning. Most students find Advanced tougher because of the unpredictable format and the multi-step problem solving, but it is fairer to say the two exams measure different skills. A strong Main scorer is not automatically a strong Advanced scorer.

You can attempt JEE Main in three consecutive years, and each year may have two sessions. So a 2027 aspirant can typically attempt it across 2027, 2028 and 2029.

A maximum of two attempts in two consecutive years. If you appear in 2027, your only other attempt would be in 2028.

Only candidates among the top performers in JEE Main - around the top 2,50,000 (all categories combined) - become eligible to register for JEE Advanced, subject to that year's official Advanced cutoff and rules.

There is generally no age limit to appear in JEE Main, but admitting institutes may have their own criteria. Confirm year-of-passing requirements on the official notification.

Yes. Droppers can appear for JEE Main within the three-year attempt window and for JEE Advanced if they have an attempt left and meet the class 12 passing-year rule.

The same two-attempts-in-two-consecutive-years rule applies. A dropper who already used both attempts cannot appear again.

A dropper can attempt JEE Main in the three consecutive years that follow (and include) their year of Class 12, with up to two sessions per year. So a candidate who passed Class 12 in 2026 can sit Main across 2026, 2027 and 2028 - that is up to six session attempts in total. After the third year, no more Main attempts are allowed. Two important caveats: the Class-12 passing year is fixed at your first eligible year, and the year you finish Advanced eligibility (two consecutive years from your first Advanced attempt) is tracked separately.

The NTA opens a short correction window after the JEE Main application close date, usually for a few days, where you can fix specific fields - photograph, signature, category, examination city preferences, and sometimes parent details. After this window closes, most fields are locked for that session. If you discover an error later, you generally cannot edit the application for the current session, though some corrections (like minor name spellings matching your board record) may be allowed through a grievance request. The safer path: review every field carefully before the first deadline and recheck during the correction window.

Carry a printed copy of your JEE Main admit card and one original photo ID - PAN card, Aadhaar, passport, voter ID, driving licence or a school ID with photograph are usually accepted. The admit card must have your photograph clearly visible, and the photograph on the admit card should match the live one taken at the centre. Some centres also ask for a passport-size photo to be pasted on the attendance sheet, so carry one spare. Do not carry any electronic device, calculator, smartwatch, notes or rough paper - rough sheets are provided at the centre. Reach the venue at least 90 minutes before reporting time.

Marks are your raw score out of 300. Percentile shows the proportion of candidates who scored at or below you in that session. The All India Rank is built from the NTA percentile, not raw marks.

The NTA percentile is a normalised score, not a raw mark. JEE Main runs in multiple shifts across several days, and the difficulty between shifts is never identical. So the NTA converts each candidate's raw marks into a percentile that represents the proportion of candidates in the same shift who scored at or below that candidate. The formula, broadly, is: percentile = 100 x (number of candidates in the shift with marks equal to or below yours) / (total candidates in the shift). After all shifts are done, the per-subject and overall percentiles are computed across the full population. Because of this, two candidates with the same raw marks in different shifts can have slightly different percentiles, and percentile is what feeds your All India Rank.

Because the exam runs in multiple shifts of varying difficulty, the NTA normalizes scores into percentiles so that candidates across shifts are compared fairly. Without normalisation, a student in an easier shift would have an unfair advantage over an equally able student in a harder shift. The percentile-based system pegs your performance against your own shift cohort first, then merges those percentiles into a single national list. It is not a bell curve and it is not a fixed cutoff - it is a relative measure, so your percentile depends both on your raw marks and on how the rest of your shift performed.

Yes, and most aspirants do. JEE Main runs two sessions in the same cycle - one around January and one around April. You can register for one or both. If you sit both, the NTA takes the better of your two percentile scores (per subject and overall) and uses only that for your All India Rank. There is no averaging and no penalty for the lower attempt. Attempting both sessions gives you a safety net: you can use Session 1 to get exam-day experience, identify weak topics from the score-card analysis, and then optimise for Session 2. The downside is fatigue and the cost of two registrations, but for serious aspirants the upside usually outweighs it.

Your best of the two NTA percentile scores is considered for ranking. There is no averaging - only the higher result is used.

The 75% rule is an admission eligibility criterion (not an exam eligibility one) used by IITs, NITs, IIITs and GFTIs through JoSAA. To be allotted a seat, you generally need at least 75% aggregate in your Class 12 board exam (65% for SC, ST and PwD candidates), or be in the top 20 percentile of successful candidates in your board for that year - whichever you satisfy. The top-20 percentile route is computed by each board separately and is published on the JoSAA / NTA notice once boards release their data. The 75% / top-20 rule is checked at the document-verification stage of JoSAA counselling, not before the exam. Exact figures and applicability are confirmed each year on the official information bulletin.

It varies sharply by NIT, branch, category and home state. As a broad indicative range: 99+ percentile is typically competitive for CSE at top NITs (Trichy, Warangal, Surathkal, Calicut) under the General-AI quota; 97-99 percentile opens up CSE / ECE seats at mid-tier NITs or non-CSE branches at top NITs; 95-97 covers most core branches at mid-tier NITs and home-state quota seats at lower-ranked NITs; below 95 the realistic targets are home-state quota at smaller NITs, IIITs and GFTIs. Always cross-check the previous year's JoSAA opening and closing ranks for the exact NIT, branch, category and AI/HS quota combination you are targeting - that data is the only reliable predictor.

A tie-breaking policy is applied (typically higher marks in Maths, then Chemistry, then Physics, and other criteria as per the official notification for that year).

For admission to IITs/NITs/IIITs/GFTIs, you generally need at least 75% aggregate in class 12 (65% for SC/ST/PwD), or be in the top 20 percentile of your board. Indicative - confirm exact figures on the official notification.

Yes. JEE Advanced is only for candidates who qualify through JEE Main and fall within the top qualifiers announced for that year.

Generally yes. JEE Advanced is more application- and concept-heavy, has an unpredictable pattern, and may include some topics beyond the JEE Main syllabus.

No. IIT admission requires qualifying JEE Advanced. JEE Main alone leads to NITs, IIITs and GFTIs through JoSAA.

Yes - OBC-NCL, SC, ST, EWS and PwD candidates get reservation in seats and relaxed cut-offs as per government norms. Keep valid certificates ready for counselling.

They overlap heavily and are both built on the class 11-12 Physics, Chemistry and Maths NCERT base, but JEE Advanced goes deeper and can include a few topics beyond Main. Check the official syllabus each year.

JoSAA (Joint Seat Allocation Authority) is the central body that conducts the common counselling for all 23 IITs, 31 NITs, 26 IIITs and the GFTIs. After both JEE Main and JEE Advanced results are out, JoSAA opens its portal where you log in, fill a choice list of institute-and-branch combinations in your preferred order, and let the algorithm allocate seats round by round based on your category, rank and the choices ahead of you. JoSAA counselling typically begins in mid-June, immediately after JEE Advanced results, and runs across five to six rounds over four to six weeks. Each round, you can accept (freeze), upgrade (float / slide), or withdraw. Dates are published on the JoSAA portal each year - the schedule is indicative.

Master NCERT first - especially for Chemistry - then add standard reference books and a lot of timed problem practice. Concept clarity plus mock practice beats passive reading.

Take regular full-length, timed mocks in the real pattern in the months before the exam - they fix time management and exam temperament, which decide ranks more than knowledge alone.

Anyone guaranteeing a rank, selling "leaked" papers, or claiming official NTA/IIT partnership for paid coaching is running a scam. Report to the official NTA or organising IIT - they cancel results for malpractice.
