What is JEE? Main, Advanced, Eligibility & Admission Process

Think of JEE as a two-stage admission pathway. JEE Main is used for admission to NITs, IIITs and other participating institutions, and it also determines eligibility for JEE Advanced. JEE Advanced is used for IIT admissions. Counselling then matches eligible candidates with available seats based on their ranks, preferences, and applicable rules. This article covers meaning, conducting bodies, differences, eligibility, admission process, and colleges.

This table gives the whole picture at a glance.

Step	What happens	Gets you into
JEE Main	Exam by NTA, held twice a year	NITs, IIITs, GFTIs
JEE Advanced	Tougher exam, only for top Main rankers	IITs
JoSAA	Online counselling and seat allotment	Your final seat

One thing to remember: your rank decides everything. A better rank means more college and branch choices.

What is JEE? (Full Form and Meaning)

JEE stands for Joint Entrance Examination. It is a national-level exam for admission to undergraduate engineering, architecture, and planning courses in India. One exam gives you one rank, and that rank is used to fill thousands of seats across the country. The exam tests Physics, Chemistry and Mathematics (for engineering). It checks whether you understand concepts and can solve problems quickly and accurately. Marks from your school exams do not replace JEE. Most top colleges use your JEE rank for admission.

When people say “JEE,” they usually mean one of two exams, JEE Main or JEE Advanced. They are separate exams with different rules, different difficulty levels and different colleges. This confuses many students, so keep it in mind as you read. Some colleges outside this system, like BITS Pilani, run their own entrance exams. JEE is the main route, but it is not the only one.

Who Conducts JEE?

Different bodies run different parts of the process.

•  JEE Main: Conducted by the National Testing Agency (NTA). It sets the dates, runs the exam in computer-based mode, and releases your score and rank.
• JEE Advanced: Conducted by one of the IITs, chosen on a rotating basis each year, under the Joint Admission Board (JAB). 

JEE Main vs JEE Advanced: What’s the Difference?

JEE Main is the first gate, and JEE Advanced is the second. The table below shows how they compare. You cannot skip Main because it is how you qualify for Advanced.

Feature	JEE Main	JEE Advanced
Conducted by	NTA	An IIT (rotating)
Purpose	NITs, IIITs, GFTIs, and entry to Advanced	Admission to IITs
Mode	Computer-based	Computer-based
Papers	Paper 1 (B.Tech), 2A (B.Arch), 2B (B.Planning). The B.Arch Drawing Test is on paper	Two compulsory papers
Difficulty	Moderate to tough	Very tough
Attempts	2 sessions a year, up to 3 years	Max 2 attempts in 2 consecutive years
Question style	Mostly direct, formula and concept-based	Multi-step, tricky, concept heavy

Simple way to think about it: Main checks if you know the topics well. Advanced checks if you can think deeply with them. A student who is strong in Main basics has a head start in Advanced prep, because both use the same subjects.

What is JEE Main?

JEE Main is held twice a year, in January and April. If you write both sessions, your better score counts. This means one bad day does not ruin your year.

Papers

• Paper 1: B.E./B.Tech. This is the one most students write.
• Paper 2A: B.Arch, with Mathematics, Aptitude and Drawing. Mathematics and Aptitude are computer-based; the Drawing Test is on paper, on an A4 drawing sheet. 
• Paper 2B: B. Planning, with Mathematics, Aptitude, and Planning questions are fully computer-based.

Paper 1 (B.E. / B.Tech)

• Exam Mode: Computer-Based Test (CBT)
• Negative Marking: −1 applies to ALL questions (both Section A and Section B).
• Selection: There are no optional questions; all 75 questions are mandatory.

Subject	Section A (MCQs)	Section B (Numerical Value)	Total Questions	Maximum Marks
Physics	20	5	25	100
Chemistry	20	5	25	100
Mathematics	20	5	25	100
Total	60	15	75	300

Paper 2A (B.Arch)

• Exam Mode: Math & Aptitude are Computer-Based (CBT); Drawing is Pen-and-Paper.
• Negative Marking: −1 applies to all Math (MCQs & Numericals) and Aptitude questions. No negative marking for the Drawing test.

Part	Subject / Section	Number of Questions	Question Type	Maximum Marks
Part I	Mathematics	25 (20 MCQs + 5 Compulsory Numericals)	Computer-Based	100
Part II	Aptitude Test	50	MCQs (Computer-Based)	200
Part III	Drawing Test	2	Pen & Paper (Offline)	100
Total		77		400

Paper 2B (B.Planning)

• Exam Mode: Computer-Based Test (CBT)
• Negative Marking: −1 applies to ALL questions across all three sections. 

Part	Subject / Section	Number of Questions	Question Type	Maximum Marks
Part I	Mathematics	25 (20 MCQs + 5 Compulsory Numericals)	Computer-Based	100
Part II	Aptitude Test	50	MCQs	200
Part III	Planning-Based	25	MCQs	100
Total		100		400

Scores and ranks

• NTA gives you a percentile score, not just raw marks. This is because the exam runs in many shifts, and percentile keeps things fair across shifts.
• Your percentile is converted into a rank, usually the Common Rank List (CRL) and a category rank.

Where your score works

• NITs, IIITs and GFTIs (centrally funded technical institutes).
• Many state engineering colleges, which use JEE Main for their own counselling.
• Entry to JEE Advanced if you are among the top 2.5 lakh rankers.

Syllabus overview: it follows Class 11 and 12 topics. In Physics, think mechanics, electricity and modern physics. In Chemistry, physical, organic and inorganic. In Maths, algebra, calculus, coordinate geometry and probability.

What is JEE Advanced?

JEE Advanced is the exam for IIT admission. Only students who qualify through JEE Main can write it.

Pattern

• Two compulsory papers, Paper 1 and Paper 2, usually held on the same day.
• Each paper covers Physics, Chemistry and Mathematics.
• Question types change from year to year. Expect single-answer, multiple-answer, numerical-value and matching-type questions, with different marking rules for different sections.

Overall Subject-Wise Weightage (Combined Paper 1 & Paper 2)

Subject	Questions in Paper 1	Questions in Paper 2	Total Questions	Total Marks
Physics	17 questions	17 questions	34 questions	120 marks
Chemistry	17 questions	17 questions	34 questions	120 marks
Mathematics	17 questions	17 questions	34 questions	120 marks
Total Combined	51 questions	51 questions	102 questions	360 marks

Typical Question Breakdown & Marking Scheme

Because the exact combination alters every year to maintain unpredictability, a subject (Physics, Chemistry, or Math) generally features a mix of the following section types:

Question Type	How It Works	Typical Marking Scheme (Correct / Incorrect)
Single Correct MCQ	Only one option out of four is correct.	+3 for correct; -1 for incorrect.
Multiple Correct MCQ (MSQ)	One or more options can be correct.	+4 if all correct; Partial marking (+1 to +3) if partial correct options are chosen; -2 for incorrect.
Numerical Value / Integer	Students calculate and enter a number/decimal using a virtual keypad.	+3 or +4 for correct; 0 (No negative marking) for incorrect.
Paragraph / Passage Based	A comprehensive text block followed by 2–3 related questions.	+3 for correct; -1 or 0 for incorrect depending on the year's rules.
Matrix Match / Match the List	Matching items from List-I to List-II.	Variable marking (usually carries negative marks).

What makes it tougher

• Questions are usually multi-step. You often need to combine two or three concepts.
• Some sections give partial marks, and some have negative marking. So smart guessing matters.
• Time pressure is high, so accuracy and speed both count.

After Advanced: Candidates seeking admission to an IIT B.Arch programme must qualify JEE Advanced and meet the applicable Architecture Aptitude Test (AAT) and admission requirements. Check the current AAT and JoSAA rules for participating programmes. 

Syllabus overview: the topics are similar to Main, but the questions go much deeper. For details, see our [JEE Advanced Syllabus] page.

JEE Eligibility Criteria

Eligibility is the set of rules that decide if you can write the exam. There are two sets, one for Main and one for Advanced. Admission eligibility (the rules for getting a seat) is slightly different, so read both.

JEE Main eligibility

• Qualifying exam: you should have passed Class 12 (or equivalent) or be appearing in it. 
• Subjects: for B.Tech, you need Physics and Mathematics, plus one of Chemistry, Biology, Biotechnology or a technical vocational subject.
• Nationality: Indian nationals and eligible foreign-national candidates may apply, subject to the applicable JEE Main rules. OCI/PIO candidates should check the specific provisions for their category and the programme to which they seek admission. 
• No minimum marks to appear: you can write JEE Main without a minimum Class 12 score. But many colleges ask for minimum marks at admission (see below).
• Admission marks rule: for NITs, IIITs and GFTIs, candidates generally need at least 75% in Class 12 (65% for SC/ST) or to be in their board’s top 20 percentile. Check the latest JoSAA rules to confirm.

JEE Advanced eligibility

• JEE Main rank: you must be among the top 2.5 lakh candidates in JEE Main (all categories together).
• Class 12 year: you must have first appeared in Class 12 in the years allowed by the brochure.
• Age limit: General-category candidates need to be born on or after October 1 of the year exactly 25 years prior to the examination year, with a five-year relaxation for SC/ST/PwD candidates (who must be born on or after October 1 of the year 30 years prior).
• Attempts: a maximum of two attempts in two consecutive years.
• Earlier IIT admission: if you have already taken admission at an IIT, you are generally not allowed to take another IIT seat through JEE.
• Class 12 marks: reports on the 75% (or top 20 percentile) rule for Advanced differ between sources.

Age limit and attempts

This table makes the rules easy to compare. 

Rule	JEE Main	JEE Advanced
Age limit	None currently	Yes (born on or after October 1 of the year exactly 25 years prior to the examination year)
Attempts	2 a year for 3 consecutive years (up to 6)	2 attempts in 2 consecutive years
Rank needed	None to write	Top 2.5 lakh in JEE Main

Common mistake: many students think “6 attempts” means 6 years. It does not. It means two sessions a year for three years. And Advanced has a separate, stricter limit.

JEE Exam Pattern Comparison

The table below puts the two exams side by side.

Feature	JEE Main	JEE Advanced
Purpose	NITs, IIITs, GFTIs and the gateway to Advanced	IITs
Papers	One paper for B.Tech	Two papers, both compulsory
Duration	3 hours	3 hours per paper
Question types	MCQ and numerical	MCQ, multi-correct, numerical, paragraph, matching
Difficulty	Moderate	High, with concept-heavy and tricky questions
Result	Percentile and rank	Marks and rank

Percentile normalisation: JEE Main runs in multiple shifts, and the papers in different shifts are never exactly equally hard. To keep things fair, scores are converted into percentiles. Your percentile shows the share of candidates in your shift who scored equal to or below you. The topper of every shift gets 100, so a tougher shift does not hurt anyone.

JEE Marking Scheme

JEE Main:

• MCQs: +4 for a correct answer, −1 for a wrong answer.
• Unanswered questions: 0 marks.
• Numerical questions: +4 for correct. Recent years removed negative marking here. See our JEE Main marking scheme page for the latest rule.

JEE Advanced: Marking depends on the question type and changes every year. Partial marking is common in multiple-correct questions. A typical scheme looks like this:

Situation	Marks
All correct options chosen	+4
Only correct options chosen, but not all	+1 per correct option (partial)
Any wrong option chosen	−2
Unanswered	0

For example, if a question has three correct options and you pick two of them with no wrong option, you may get +2. If you pick two correct options and one wrong one, you lose 2 marks.

Tips to avoid negative marking:

• Attempt a question only when you can eliminate at least two options.
• Do not guess blindly in MCQs, since one wrong answer cancels out a quarter of a correct one.
• In the first round, solve the questions you are sure about, and come back to the doubtful ones later.
• Practise with timed mocks to find out your safe accuracy level.

JEE Syllabus

JEE Main is based on the Class 11 and Class 12 syllabus. Here are the main chapters by subject.

Subject	Class 11 Highlights	Class 12 Highlights
Physics	Units and Measurements, Kinematics, Laws of Motion, Work-Energy-Power, Rotational Motion, Gravitation, Thermodynamics, Oscillations and Waves	Electrostatics, Current Electricity, Magnetism, EMI and AC, Optics, Modern Physics, Semiconductors
Chemistry	Basic Concepts, Atomic Structure, Chemical Bonding, Thermodynamics, Equilibrium, Organic Basics, Hydrocarbons	Solutions, Electrochemistry, Kinetics, d- and f-block, Coordination Compounds, Haloalkanes, Alcohols, Aldehydes and Ketones, Biomolecules
Maths	Sets, Complex Numbers, Quadratic Equations, Sequences and Series, Permutations, Binomial Theorem, Straight Lines, Circles, Conic Sections	Matrices, Determinants, Limits, Continuity, Differentiation, Integration, Differential Equations, Vectors, 3D Geometry, Probability

B.Arch and B.Planning: Paper 2A needs Maths, Aptitude (visual and architectural awareness) and Drawing. Paper 2B needs Maths, Aptitude and Planning topics such as urban development, social awareness and basic geography.

JEE Advanced syllabus: It covers the same broad areas as Main, but questions go much deeper. For example, you get tougher problems in rotational mechanics, thermodynamics, electrochemistry, organic mechanisms, calculus and 3D geometry, along with topics that are only lightly touched in Main.

The table below compares the two syllabi.

Aspect	JEE Main	JEE Advanced
Scope	NCERT-based Class 11 and 12	Same topics, with greater depth
Question style	Direct and formula-based	Multi-concept and analytical
Extra depth	Limited	Advanced problem-solving in Maths and Physics

High-weightage chapters: Calculus, Coordinate Geometry and Algebra in Maths. Mechanics, Electrostatics, Current Electricity and Modern Physics in Physics. Physical Chemistry (Equilibrium, Electrochemistry), Organic Chemistry and Coordination Compounds in Chemistry.

Class 11 vs Class 12 split: Questions come from both classes in roughly equal measure, so do not skip Class 11. Many Class 12 chapters depend on it.

Best Books for JEE

The right books save you time, and you do not need dozens of them. Here is a book-wise list.

Subject	Basics	Practice and Advanced
Physics	NCERT, HC Verma	DC Pandey, Irodov (for Advanced)
Chemistry	NCERT (a must for Inorganic)	O.P. Tandon (Physical and Organic), J.D. Lee (Inorganic), MS Chauhan (Organic)
Maths	NCERT, RD Sharma	Cengage series, Arihant (Skills in Maths), Amit M Agarwal

For Advanced: Add more advanced problem books, such as Irodov for Physics and Cengage’s advanced volumes for Maths.

Role of NCERT: It is the base for Chemistry, especially Inorganic. Read it line by line, because many JEE questions come straight from its examples and facts.

PYQs and mocks: Solve previous-year papers chapter by chapter, then attempt full mocks in exam conditions.

JEE Admission Process: Step by Step

The path from “I want to write JEE” to “I have a seat” has three phases. Here they are in order.

1. Registration and exam

• Register for JEE Main on the NTA website. Fill in your details, upload photos and documents, and pay the fee.
• Use the correction window (if NTA opens one) to fix mistakes.
• Download your city intimation slip, then your admit card.
• Write the exam in computer-based mode.

2. Result

• Check the provisional answer key. You can challenge answers within the window.
• Get your NTA scores, percentile and All India Rank.
• If you are in the top 2.5 lakh, register separately for JEE Advanced. Registration is on the Advanced website, not NTA’s.
• Write the two papers of Advanced and check your rank.

3. JoSAA counselling and seat allotment

• Register on the JoSAA portal using your JEE details.
• Fill in your choices. Pick colleges and branches in the order you prefer them. You can add many choices. More choices mean more safety.
• Mock allotments: JoSAA runs trial rounds so you can see where your rank might land. Use them to adjust your list.
• Seat allotment rounds: JoSAA runs several rounds. After each round, you see your allotted seat.
• Respond to your seat: you can usually freeze (accept and stop), float (accept but hope for better) or slide (stay in the same college but try for a better branch). The portal explains these options each round.
• Documents and fee: upload documents, pay the seat acceptance fee, and complete the process before the deadline.
• Report to your college and finish admission formalities.

Documents Required for JEE

At registration:

JEE Advanced	May 2027
JEE Advanced result	June 2027
JoSAA counselling starts	June 2027

JEE Result

JEE Main result: It is released on the official website after each session. Your scorecard shows your percentile for each subject and overall, along with your rank. The final rank list is released after both sessions. If there is a tie, tie-breaking rules apply, and these usually favour higher scores in Maths, then Physics, then Chemistry.

JEE Advanced result: It shows your marks, All India Rank (AIR) and category rank. Candidates who appear for the Architecture Aptitude Test (AAT) for B.Arch at IITs get a separate AAT result.

Steps to check:

1. Visit the official website.
2. Click the result link.
3. Enter your application number and password (or date of birth).
4. Download and save your scorecard.

Answer key challenge window: After the provisional answer key is released, you get a short window to challenge answers by paying a fee per question. Keep your proof ready, and see our JEE Main answer key page for the step-by-step process.

The table below gives an example of how marks, percentile and rank relate. These numbers are only illustrative.

Marks (out of 300)	Approx. Percentile	Approx. Rank
250+	99.9+	Top few hundred
180	About 99	Around 10,000
100	About 90	Around 1 lakh

The exact mapping changes every year, depending on paper difficulty. Our marks vs percentile page has the latest trends.

JEE Cutoff

JEE Main qualifying cutoff: This percentile cutoff decides who can appear in JEE Advanced. In recent years, it was around 90+ for General, lower for OBC-NCL and EWS, and lowest for SC, ST and PwD.

JEE Advanced qualifying cutoff: Candidates must score a minimum in each subject and a minimum aggregate. The minimums are set separately for each category.

JoSAA opening and closing ranks: These show the best and the last rank at which a seat in a branch was given in a round. The closing rank is the one to watch, since it tells you who got in.

Here is a sample table to explain the concept.

Institute	Branch	Opening Rank	Closing Rank
Sample IIT	CSE	100	1,200
Sample IIT	Mechanical	2,000	6,500
Sample NIT	CSE	1,500	9,000

JEE Seats

JEE seats are spread across four types of institutes: IITs, NITs, IIITs and GFTIs (Government Funded Technical Institutes). Together, there are over 120 institutes and roughly 60,000+ seats, with IITs offering about 18,000 and NITs about 25,000 or more. Check our JEE seats page for the latest seat matrix.

Branch-wise distribution: Each institute splits its seats across branches. Popular branches like CSE and ECE have fewer seats than demand, so their cutoffs are harsher.

Home State vs Other State quota (NITs): At each NIT, half the seats are kept for candidates from that state (Home State), and the rest are for all other candidates (Other State).

How seats change every year: New institutes, new branches and intake increases alter the total. The seat matrix is published on the JoSAA website before counselling begins, and we update our seats page as soon as it is out.

Reservation and Category Seats

Reserved seats follow the national pattern.

Category	Reservation
General (Open)	Remaining seats
OBC-NCL	27%
SC	15%
ST	7.5%
EWS	10%
PwD	5% (horizontal)

Female supernumerary seats: Seats are added for women so the number of women in a programme increases without reducing seats for others. Many institutes aim for about 20%.

Category rank vs CRL: Your Common Rank List (CRL) rank is your overall rank. Your category rank is your position within your own category. Reserved-category candidates are allotted seats on category rank, but they can also compete in the open pool using their CRL.

JoSAA Counselling

JoSAA (Joint Seat Allocation Authority) runs counselling for IITs, NITs, IIITs and GFTIs. Anyone who qualified in JEE Main (for NITs, IIITs and GFTIs) or in JEE Advanced (for IITs) can take part.

Step-by-step process:

1. Registration: Create an account and fill in your details.
2. Choice filling: List your preferred college-branch combinations in order of priority.
3. Mock allotments: Two mock rounds show a trial result, so you can adjust your choices.
4. Seat allotment rounds: Several rounds are run, and allotment is based on rank and your choice order.
5. Freeze, Float or Slide: Freeze means you accept the seat and stop. Float means you keep the seat but want a better college in the next round. Slide means you want a better branch in the same college.
6. Document upload: Upload your documents for verification.
7. Fee payment: Pay the seat acceptance fee to confirm your seat.
8. Reporting: Report to the allotted institute with originals.

Choice filling tips:

• Add as many choices as possible, from dream to safe.
• Keep your list in the order of your true preference, not by guessed cutoffs.
• Research branch scope and college quality, not just the brand name.

Important dates: Counselling usually begins after the JEE Advanced result. See our JoSAA counselling page for the full schedule. After JoSAA, you can also look at CSAB special rounds for vacant seats, and your own state counselling for state colleges.

Colleges You Can Get Through JEE

Your examination determines which college family you will become a part of:

• IITs (23): through JEE Advanced and JoSAA.
• NITs, IIITs and GFTIs: through JEE Main and JoSAA. Together they make up more than 100 institutes.
• State engineering colleges: many states use JEE Main scores or ranks for admission, through their own counselling.

How to choose smartly:

• Look at previous years’ opening and closing ranks.
• Think about the branch first, then the college.
• Check placements, faculty and location.
• Keep a few realistic options in your list.

A good rank in JEE Main still gives you strong options. Do not feel that only IITs are “good.”

College Fees, Placements and Career Scope

Fees differ widely between institute types. These are approximate yearly tuition amounts.

Institute Type	Approx. Tuition Per Year
IITs	₹2–2.5 lakh
NITs	₹1.25–1.5 lakh
IIITs	₹1.5–3 lakh

Hostel and mess costs are extra. Fee waivers and scholarships exist for eligible candidates.

Placements: IITs usually report the highest average packages, followed by top NITs and IIITs. Numbers change every year, so see our placements page for the latest figures.

Branch-wise scope:

• CSE/IT: Software, AI, data science, product roles
• ECE/EEE: Electronics, VLSI, telecom, power
• Mechanical: Core manufacturing, automotive, robotics
• Civil: Construction, infrastructure, government jobs

Other Engineering Entrance Exams

JEE Preparation Tips

When to start: Starting in Class 11 gives you the most time, but a focused Class 12 start also works. What matters is consistency.

Basic study plan:

• Finish the syllabus first, chapter by chapter.
• Spend more time on weak and high-weightage chapters.
• Keep a short daily slot for each subject.

Mocks and PYQs: Attempt regular full-length mocks and analyse every mistake. Solve previous-year papers to understand the question style.

Revision strategy: Make short notes and formula sheets, and revise them weekly. In the last two months, spend more time on mocks than on new topics.

For droppers: A drop year can work if you use it well. Find out why you missed the first time, fix those gaps, and follow a strict plan. Take care of your health and stay positive. Our JEE preparation tips page has a ready study plan to get you started.

Conclusion and CTA

So, what is JEE exam? The Joint Entrance Examination is India's main entrance exam for getting into top engineering colleges.
