JEE Main 2026 Exam Schedule

The National Testing Agency (NTA) has announced the following dates for JEE Main 2026:

Session 1: January 21 – January 30, 2026

Session 2: April 1 – April 10, 2026

This means that Session 1 will occur before the CBSE Class 12 Boards, and Session 2 will take place after the CBSE exams conclude.

Understanding the Gap Between CBSE Board and JEE Main 2026

After the CBSE Board Exams for major subjects will end on March 27, providing students with approximately 4–5 days before JEE Main Session 2 that begins on April 1, 2026.

This short gap is extremely valuable for students as it’s the final window to revise JEE concepts, solve practice papers, and strengthen weaker topics.

Key Takeaways:

• No clash between CBSE Boards and JEE Main Session 2.
• 4–5 days of transition for final JEE revision.
• Ideal for students to focus purely on JEE after Boards without distractions.

How to Balance CBSE Board Exam and JEE Main Preparation

1. Divide Study Time Strategically

• During October to January, focus 60% on JEE syllabus and 40% on board theory.
• After JEE Main Session 1 (January), shift to 80% boards and 20% JEE until exams begin.

2. Align Common Topics

Subjects like Physics, Chemistry, and Mathematics overlap between CBSE and JEE.

Focus on:

• Conceptual clarity for boards.
• Numerical and application-based questions for JEE.

This way, your preparation serves both purposes efficiently.

3. Use JEE Session 1 as a Mock Run

Treat JEE Main Session 1 as a performance check.

It will:

• Reveal your weak areas before the boards.
• Help refine your approach for Session 2 after March.

4. Keep Revision Notes Ready

Make brief JEE revision notes with formulas, reaction mechanisms, derivations, and important concepts before boards start. During the post-board gap, they will save time.

Planning your preparation month by month helps you stay organized and confident. Here’s a detailed strategy on how to balance CBSE Class 12 Board Exams 2026 and JEE Main 2026 efficiently.

October–December 2025: Focus on Core JEE + CBSE Revision

This is the testing month when you will have your first real attempt at JEE Main 2026. Treat this as a mock run to evaluate your strengths and weaknesses.

Key Strategies:

• Attempt JEE Main Session 1 (January 21–30, 2026) with full preparation.
• Analyze your performance and identify weak topics for improvement.
• Do not panic over results; instead, use them as feedback for Session 2.
• Continue light board exam revision during breaks.

➡ Goal: Gain real exam experience and refine your study plan for the next phase.

February–March 2026: Focus on CBSE Class 12 Board Exams

This period is dedicated to CBSE Class 12 Board Exam 2026 preparation. Concentrate on theory, written answers, and presentation skills — which carry high marks in boards.

Key Strategies:

• Practice previous year CBSE papers and sample papers daily.
• Revise definitions, derivations, and key formulas from NCERT textbooks.
• Join short doubt-clearing sessions if needed for tricky topics.

➡ Goal: Score well in boards while keeping your JEE basics intact.

Post-March 27, 2026: Target JEE Main Session 2

After the CBSE Board Exams conclude on March 27, you’ll have about 4–5 days before JEE Main Session 2 (April 1–10, 2026). Use this window for focused revision and mock practice — not for new topics.

Key Strategies:

• Revise important formulas, concepts, and shortcuts.
• Attempt two full-length mock tests daily and analyze your errors.
• Practice time-bound problem-solving to improve speed and accuracy.
• Maintain a healthy routine — rest, eat well, and stay calm.

➡ Goal:  Enter JEE Main Session 2 with maximum confidence and clarity.

Final Tip: Use the Gap Wisely

The 4–5 day gap between CBSE Board Exams 2026 and JEE Main 2026 Session 2 is short but powerful. Use it for intense revision, mock testing, and formula brushing. Do not start any new topics. Remember, consistency and smart scheduling are the real game-changers. With the right strategy, you can excel in both CBSE Boards and JEE Main 2026 with confidence.
