The Joint Entrance Examination (JEE) is the engineering entrance examination conducted for admission to various engineering colleges in India. It is constituted by two different examinations: JEE Main and JEE Advanced. JEE Main is the preliminary test that qualifies students for JEE Advanced, which is the gateway for admission to the prestigious Indian Institutes of Technology (IITs).
JEE was introduced to streamline the engineering admission process and eliminate multiple entrance examinations. The exam is conducted in computer-based mode for JEE Main and both computer-based and pen-paper modes for JEE Advanced. JEE has become the primary engineering entrance test for admission to all major engineering colleges in India, including NITs, IIITs, and other centrally funded technical institutions.
JEE 2025 will follow the same pattern as previous years with multiple-choice questions from Physics, Chemistry, and Mathematics. JEE Main is conducted twice a year (January and April sessions), while JEE Advanced is conducted once a year. The exam is conducted in multiple languages to accommodate students from various linguistic backgrounds across India.
The importance of JEE in the Indian education system cannot be overstated. It serves as the primary determinant for engineering aspirants seeking admission to prestigious institutions. The competition is intense, with over 10 lakh students appearing for approximately 25,000 available seats in IITs. Success in JEE requires not only academic excellence but also strategic preparation, time management skills, and psychological preparedness.
JEE 2025 will continue to be based on the NCERT curriculum for Classes 11 and 12, making NCERT textbooks the most crucial resource for preparation. The exam tests conceptual understanding, application skills, and problem-solving abilities rather than rote memorization. With the right preparation strategy and resources, students can achieve their dream of pursuing a career in engineering.

JEE Main Previous Year Questions (PYQs) are arguably the most valuable resource for aspirants. Solving PYQs from the last 5-10 years helps in understanding the exam pattern, the type and difficulty level of questions asked, the frequency and weightage of various topics, and the recurring concepts. It moves preparation from theoretical learning to applied problem-solving. Analyzing PYQs also helps identify strong and weak areas, allowing for targeted revision. Many questions or concepts are often repeated with slight modifications. Practicing PYQs under timed conditions is the best simulation for the actual exam, building speed, accuracy, and stamina. The NTA officially provides PYQs on its website, and numerous coaching institutes also compile them with detailed solutions.
| Benefit | Description |
|---|---|
| Pattern Familiarity | Get accustomed to the structure and style of questions. |
| Topic Weightage | Identify which chapters are most important historically. |
| Concept Revision | Application of learned concepts to real exam problems. |
| Time Management | Practice completing 90 questions within the 3-hour limit. |
| Confidence Building | Reduces exam anxiety by providing a realistic practice ground. |

JEE Main Session 2 is the second and final opportunity for candidates to attempt the exam in the annual cycle. It is typically held in April. Candidates can choose to appear in only Session 1, only Session 2, or both. The best of the two percentile scores is considered for preparing the final All India Rank (AIR) and for determining eligibility for JEE Advanced (top 2.5 lakh rank holders). Session 2 is crucial for those who felt they underperformed in Session 1 due to health issues, exam-day problems, or inadequate preparation. It also benefits candidates who missed Session 1 entirely. The pattern, syllabus, and difficulty level are intended to be comparable to Session 1, though normalization ensures fairness across sessions. Registration for Session 2 is a separate process, often opening after the declaration of Session 1 results.
| Aspect | Session 1 | Session 2 |
|---|---|---|
| Typical Month | January | April |
| Purpose | First attempt, sets a baseline. | Improvement attempt or first attempt for late starters. |
| Best Score Considered | Yes, the higher percentile from either session is used for the final rank. | |
| Registration | Starts ~December of previous year. | Starts ~February/March (after Session 1 results). |
The relationship between JEE Main marks and percentile is not linear or fixed; it varies each year depending on factors like the difficulty of the paper, the number of candidates, and the performance of the top scorers. A percentile indicates the percentage of candidates who have scored equal to or less than a particular score. For example, a 99 percentile means you have scored better than 99% of the candidates. Generally, to secure a percentile above 99, a candidate needs a score very close to the maximum, often above 250+/300. The normalization process used by NTA ensures that percentiles are comparable across different shifts and sessions, making the competition fair. Percentile is the ultimate metric for ranking, not raw marks.
| Total Marks (out of 300) | Expected Percentile Range (Approx.)* | Possible Rank Range |
|---|---|---|
| 250 - 300 | > 99.5 | 1 - 5000 |
| 200 - 249 | 97 - 99.5 | 5,000 - 25,000 |
| 150 - 199 | 90 - 97 | 25,000 - 1,00,000 |
| 100 - 149 | 75 - 90 | 1,00,000 - 2,50,000 |
| Below 100 | < 75 | > 2,50,000 |
| *This is a rough estimation. Actual percentiles depend on the specific session's difficulty and candidate pool. | ||
The JEE Main B.E./B.Tech (Paper 1) examination is conducted for a total of 300 marks. This total is evenly distributed across the three subjects: Physics, Chemistry, and Mathematics, each contributing 100 marks. The 100 marks per subject come from 30 questions, with a specific marking scheme: +4 for a correct answer, -1 for an incorrect MCQ, and 0 for an unattempted or incorrect NVQ. The "total marks" a candidate secures is their raw score out of 300. However, for ranking purposes, this raw score is converted into a percentile score through a statistical normalization process. This total marks framework defines the scale of the exam and is a key parameter for setting preparation targets and evaluating mock test performances.
| Subject | Number of Questions | Marks per Question | Total Subject Marks |
|---|---|---|---|
| Physics | 30 | +4 (Correct), -1 (Incorrect MCQ), 0 (NVQ) | 100 |
| Chemistry | 30 | +4 (Correct), -1 (Incorrect MCQ), 0 (NVQ) | 100 |
| Mathematics | 30 | +4 (Correct), -1 (Incorrect MCQ), 0 (NVQ) | 100 |
| GRAND TOTAL | 300 | ||
