If you are preparing for JEE Main or JEE Advanced 2027, you need clarity on the syllabus, marking scheme, attempts and the way your JEE Main score is calculated. The problem is that the official 2027 details are not out yet.
As of now, the latest official 2026 syllabus and exam rules are the best reference for planning your preparation. We have explained them below so you know what currently stands, and we will update this page the moment anything new is officially announced for 2027.
JEE Main vs Advanced: What Is the Difference?
The two exams share Physics, Chemistry and Mathematics but have different purposes and examination formats, as detailed on the official JEE Main exam and JEE Advanced exam pages.
| Feature | JEE Main | JEE Advanced |
|---|---|---|
| Purpose | Admission to NITs, IIITs and other participating institutes; eligibility for JEE Advanced | Admission to IITs |
| Subjects | Physics, Chemistry, Mathematics | Physics, Chemistry, Mathematics |
| Mode | Computer Based Test | Computer Based Test |
| Papers | Paper 1 for B.E./B.Tech.; Paper 2 for B.Arch./B.Planning | Two compulsory papers |
| Duration | 3 hours for Paper 1 | 3 hours per paper |
| Attempts | Two sessions in a year under the 2026 rules | Maximum two attempts in two consecutive years |
| Score | NTA Score/percentile | Marks and rank |
JEE Main Paper 1 covers Mathematics, Physics and Chemistry with equal weightage — see the full JEE Main exam pattern for the section-wise breakdown. JEE Advanced consists of two compulsory papers, with each paper covering all three subjects; refer to the JEE Advanced exam pattern page for details.
JEE Syllabus 2027: Main vs Advanced
The broad PCM foundation is common to both examinations but the two syllabi should not be treated as identical.
The latest official JEE Main syllabus covers Mathematics, Physics and Chemistry for Paper 1 — see the subject-wise breakdowns for JEE Main Physics syllabus, JEE Main Maths syllabus and JEE Main Chemistry syllabus. NTA has published the 2026 syllabus on the official JEE Main website.
JEE Advanced syllabus has its own official coverage of Physics, Chemistry and Mathematics — explore the JEE Advanced Physics syllabus, JEE Advanced Maths syllabus and JEE Advanced Chemistry syllabus pages. The 2026 syllabus is provided as Annexure I of the official Information Brochure.
The more important difference is how students are expected to apply these concepts. JEE Main requires speed and accuracy across a large number of candidates and multiple shifts. JEE Advanced uses two papers and varied question formats to test deeper understanding and problem-solving ability.
JEE Main Exam Pattern 2027
Under the latest official 2026 pattern (full details on the JEE Main exam pattern page), Paper 1 for B.E./B.Tech. has:
- Mathematics: 25 questions and 100 marks
- Physics: 25 questions and 100 marks
- Chemistry: 25 questions and 100 marks
- Total: 75 questions and 300 marks
- Section A: 20 MCQs per subject
- Section B: 5 numerical-value questions per subject
- Correct answer: +4 marks
- Incorrect answer: -1 mark
- Unanswered question: 0 marks
- Duration: 3 hours
- Mode: Computer Based Test
Negative marking applies to both Section A and Section B under the 2026 Paper 1 pattern.
JEE Advanced Exam Pattern 2027
Under the latest official 2026 rules (see the JEE Advanced exam pattern page), JEE Advanced has two compulsory papers. Each paper is three hours long and contains Physics, Chemistry and Mathematics.
Unlike JEE Main, students should not assume that JEE Advanced will use one fixed marking scheme every year. The question papers can contain different question types with their own marking rules. The official brochure also specifies that negative marks may apply to some incorrect responses. This makes question-format practice particularly important for Advanced preparation — practise with the JEE Advanced sample papers and JEE Advanced previous year question papers.
How Many Attempts Are Allowed?
For JEE Main, the latest 2026 structure provided two examination sessions — check the JEE Main important dates and JEE Main exam dates pages for session-wise timelines. Candidates could appear in either session or both. If a candidate appeared in both, the better NTA Score was considered for the merit list and ranking.
For JEE Advanced, the latest official rule allows a candidate to attempt the examination a maximum of two times in two consecutive years. Track key dates on the JEE Advanced important dates and JEE Advanced registration date pages.
There is also an important connection between the two examinations: under the 2026 rules, candidates had to meet the JEE Main eligibility criteria and rank among the top 2,50,000 successful candidates in the JEE Main B.E./B.Tech. paper to satisfy the JEE Advanced eligibility criteria.
JEE Main Normalization Process Explained
JEE Main can be conducted across multiple shifts. Since different shifts may have slightly different difficulty levels, NTA uses a percentile-based normalization process rather than comparing raw marks alone.
The raw marks obtained by candidates are converted into percentile scores based on their relative performance within their shift. The percentile represents the percentage of candidates in that shift who scored equal to or below the candidate.
For example, a 99 percentile does not mean that a student scored 99% marks. It means the student’s performance was equal to or better than 99% of candidates in the relevant comparison. NTA calculates the percentile to seven decimal places to reduce bunching and ties. For candidates appearing in both JEE Main sessions, the better NTA Score is considered under the latest official rules — check historical trends on the JEE Main cut-off page.
How Should You Prepare for JEE Main and Advanced Together?
You do not need two completely separate preparation strategies.
Start with the common PCM concepts in the JEE syllabus 2027. Once your fundamentals are clear, practise JEE Main mock tests and JEE Main previous year question papers to build speed and accuracy. Then move towards more complex, multi-step problems using JEE Advanced mock tests for Advanced-level practice.
- Complete the concept and understand its applications.
- Practise standard questions.
- Add timed JEE Main practice.
- Analyse mistakes and revise weak areas using the JEE Main question paper analysis.
- Practise Advanced-level problems.
- Attempt different question formats.
- Take full-length tests for both examinations.
Do not wait until the JEE Main examination is close to start timed practice. Speed and accuracy need to be developed gradually — a structured JEE crash course can help in the final revision phase.
Exam-Day and Result Essentials
Once you have registered through the JEE Main application form or JEE Advanced application form, keep these milestones on your radar:
- Download your JEE Main admit card or JEE Advanced admit card before exam day.
- Review the JEE Main dress code and exam-centre guidelines.
- Check answers against the JEE Main answer key and solutions or JEE Advanced answer key and solutions.
- Track your performance via the JEE Main exam result or JEE Advanced exam result.
- Plan your seat allotment through JEE Main counselling or JEE Advanced counselling.

Is the JEE syllabus 2027 officially released?
As of now, the official 2027 syllabus has not been released. Students can use the latest official 2026 JEE Main and JEE Advanced syllabi for preparation. Any confirmed 2027 changes will be updated here.
What is the main difference between JEE Main and JEE Advanced?
JEE Main is used for admission to NITs, IIITs and other participating institutions and also determines eligibility for JEE Advanced. JEE Advanced is used for admission to IITs. Their question formats and testing approach also differ.
How many times can I appear for JEE Main and JEE Advanced?
Under the latest 2026 rules, JEE Main provides two sessions in the year, while JEE Advanced allows a maximum of two attempts in two consecutive years. The final 2027 rules will be confirmed in the official documents.
What does normalization mean in JEE Main?
Normalization converts raw marks from different shifts into percentile scores so candidates can be compared fairly despite possible differences in shift difficulty. A percentile is not the same as percentage marks.
Will the JEE Main and JEE Advanced exam pattern change for 2027?
The 2027 pattern has not been officially announced yet. The latest 2026 rules on the JEE Main exam pattern and JEE Advanced exam pattern pages can be used for preparation for now. If NTA or the JEE Advanced authorities announce any changes for 2027, we will update this page here.
