JEE Main for B.E./B.Tech is a computer-based test designed to assess your grasp of Physics, Chemistry, and Mathematics at the 10+2 level. Understanding the exam pattern is the first step to building a smart preparation strategy. Here’s what you need to know — no fluff, just the facts.
Exam Structure Overview
The test consists of three sections — Physics, Chemistry, and Mathematics — each carrying equal weight. The total duration is 3 hours. Each section has two types of questions: Multiple Choice Questions (MCQs) and Numerical Value Questions.
- Total questions: 90 (30 per subject)
- Questions to attempt: 75 (25 per subject)
- Total marks: 300
- Time allowed: 3 hours (180 minutes)
You are required to answer 25 questions per subject. The remaining 5 questions in each section are optional — you can choose which 25 to attempt.
Section-wise Breakdown
Physics (Section A & B)
- Section A: 20 MCQs (each 4 marks)
- Section B: 10 Numerical Value questions (each 4 marks) — attempt any 5
- Total marks: 100 (for 25 attempted questions)
Chemistry (Section A & B)
- Section A: 20 MCQs (each 4 marks)
- Section B: 10 Numerical Value questions (each 4 marks) — attempt any 5
- Total marks: 100 (for 25 attempted questions)
Mathematics (Section A & B)
- Section A: 20 MCQs (each 4 marks)
- Section B: 10 Numerical Value questions (each 4 marks) — attempt any 5
- Total marks: 100 (for 25 attempted questions)
Marking Scheme
- Correct answer (MCQ): +4 marks
- Correct answer (Numerical Value): +4 marks
- Incorrect answer (MCQ): -1 mark (negative marking)
- Incorrect answer (Numerical Value): No negative marking — you get 0 for a wrong answer
- Unanswered: 0 marks
Numerical Value questions require you to enter a numeric answer (positive integer or decimal up to two decimal places). There is no negative marking for these, so it’s always worth attempting them if you have any idea.
Pass Criteria / Qualifying Marks
JEE Main does not have a fixed pass percentage. Instead, candidates are ranked based on their NTA score (normalized across multiple sessions). The qualifying cut-off for JEE Advanced (for IIT admission) is announced after each session. Typically, the qualifying percentile for general category is around 85-90 percentile, but this varies each year. For B.E./B.Tech admission via JoSAA, seat allocation depends on your All India Rank (AIR) and category rank. Always check the official JEE Main website for the latest cut-off trends.
Important Points to Remember
- The exam is conducted in multiple sessions (usually February, March, April, and May). You can appear in up to two sessions, and the best score is considered.
- The question paper is available in 13 languages (English, Hindi, Assamese, Bengali, Gujarati, Kannada, Marathi, Malayalam, Odia, Punjabi, Tamil, Telugu, and Urdu).
- Calculator is not allowed. Only a virtual on-screen calculator is provided.
- No negative marking for Numerical Value questions — a strategic advantage.

How to Use This Pattern for Preparation
- Time management: Allocate roughly 1 minute per MCQ and 2 minutes per Numerical Value question. Practice with a timer.
- Prioritize Numerical Value questions: Since there’s no negative marking, attempt all 5 in each section if you have even partial knowledge.
- Focus on accuracy for MCQs: A wrong answer costs you 1 mark, so avoid random guessing.
- Mock tests are essential: Simulate the exact exam environment to build speed and reduce anxiety.

Common Mistakes to Avoid
- Skipping Numerical Value questions: They are free from negative marking — attempt them.
- Overthinking time: Stick to your planned time per question. Move on if stuck.
- Ignoring the optional choice: You can skip up to 5 questions per section — use that flexibility wisely.
