10 Common Silly Mistakes to Avoid in IIT JEE 2026

Hello

If you want to get admission in IIT Delhi, then you will score well in JEE Advanced. Only the JEE Mains score is not sufficient to get admission in the IIT Delhi. You need to score 250+ marks for the general category in CSE. For the reservation category, you also need to score much higher marks and give your best performance. If you score quite well in JEE Advanced, then you will have a chance to get admission through JOSAA counselling.

Thank you

To score good marks in JEE Mains, you need a strong plan, consistent study habits and smart practice. First, finish the entire JEE syllabus from NCERT Class 11 and 12 textbooks, because these are the foundation for questions asked in the exam. After completing the basics, choose good quality reference books for Physics, Chemistry and Mathematics to build problem-solving skills and deepen your understanding. Make a weekly study plan where each day is divided into theory study, problem practice and revision of earlier topics.

Regularly solve previous years’ JEE Main papers and take timed mock tests to improve your speed and accuracy. Analyse every test you take, understand your mistakes and work on weak areas instead of only doing new questions. In subjects like Physics and Mathematics, practising a variety of numerical problems is important, while in Chemistry focus on concepts and reactions that are frequently asked. Revision is crucial, so dedicate time every week to revisit older topics and short notes that you make while preparing.

Stay consistent, avoid last-minute cramming, and maintain good health with adequate sleep and breaks during study. With disciplined planning, regular practice and careful revision, you can significantly improve your JEE Main score. All the best.

Achieving a JEE Rank of below 100 in JEE Main and Advanced 2027 requires a disciplined, two-year preparation strategy starting from Class 11. Your study plan must integrate competitive exam preparation with your school academics:

Phase 1: Class 11 (Foundation Building and Conceptual Clarity)

• Syllabus Completion: Dedicate this year to rigorously completing the entire Class 11 NCERT syllabus for Physics, Chemistry, and Mathematics (PCM). Focus heavily on fundamental topics like Mechanics (Physics), General Organic Chemistry (GOC) and Chemical Bonding (Chemistry), and Calculus basics (Maths).

• Concept Mastery: Do not rush. Master concepts thoroughly before moving to problems. Use standard JEE reference books and ensure you solve all NCERT examples and exercises first.

• Practice: Allocate 60% of your study time to concept building and 40% to problem-solving. Practice JEE Main Previous Year Questions (PYQs) immediately after completing a chapter to gauge the exam pattern.

Phase 2: Class 12 (Advanced Problem Solving and Revision)

• Advanced Topics: Complete the Class 12 syllabus by November 2026, focusing on high-weightage topics like Electrostatics, Modern Physics, and Electrochemistry.

• Revision & Mocks: Reserve the period from December 2026 to January 2027 solely for mock tests and revision. Start taking full-length JEE Main mock tests (3 per week) under strict timed conditions. Analyze each mock test thoroughly to eliminate repeated errors.

• Target JEE Advanced: After the JEE Main attempts in early 2027, shift focus entirely to JEE Advanced PYQs and challenging, multi-concept problems, taking at least 2 JEE Advanced mock tests per week.

The last 30 days before the JEE Main exam should be dedicated entirely to revision, practice, and error analysis, shifting focus away from learning new concepts.

Here is a concise, 30-day study plan to maximize your score:

1. Revision Strategy (Weeks 1-3)

• Prioritize High-Weightage Topics: Spend 70% of your revision time reviewing the most scoring and frequently tested chapters (e.g., Modern Physics, Chemical Kinetics, p-Block elements, Vectors & 3D Geometry). Use your short notes and flashcards for quick review, focusing on formulas, key mechanisms, and definitions.

• Physics & Maths: Master all formulas and derivations. Practice at least 20 numerical problems daily, emphasizing speed and calculation accuracy.

• Chemistry: Dedicate 50% of your Chemistry time to Inorganic (NCERT-based) and Organic (name reactions, reagents, mechanisms) concepts.

2. Mock Tests & Analysis (Daily)

• Daily Mock Test: Solve one full-length JEE Main Mock Test every day (3 hours) under strict exam conditions (9 AM–12 PM or 3 PM–6 PM).

• Error Analysis (Crucial): Immediately after the test, spend 2-3 hours analyzing your performance:

  • Identify every incorrect or unattempted question.

  • Determine the reason for the error (Conceptual mistake, calculation error, or time pressure).

  • Revisit the concept from your notes/NCERT text to correct the mistake permanently.

3. Final Week Focus (Last 7 Days)

• Stop Learning New Topics: Absolutely avoid picking up new, complex chapters.

• PYQ Sprint: Revisit only the last 3 years' JEE Main Previous Year Questions (PYQs). Mark any previously incorrect questions and solve them again.

• Mindset: Focus on maintaining confidence, getting proper sleep, and using the revision breaks for physical activity to keep your mind fresh.

The most effective way to prepare for JEE Main 2026 is by focusing on the most important Previous Year Question Papers (PYQs), which highlight high-weightage and frequently repeated questions across Physics, Chemistry, and Mathematics. Since the exam strongly tests NCERT concepts, mastering these PYQs is essential for predicting the question pattern and improving your time management. https://engineering.careers360.com/articles/jee-mains-chapterwise-pyq-previous-year-questions-solutions-pdf
