Aspirants preparing for JEE Advanced 2026, a critical step toward securing admission to B.Tech programs at IITs, must navigate its high-stakes and competitive nature with precision. Unlike JEE Main, JEE Advanced demands deeper conceptual understanding and analytical skills, making it essential to avoid common errors that can derail performance. Despite rigorous preparation with past papers and mock tests, candidates often falter due to nervousness or oversight, impacting their scores.

Common Mistakes to Avoid When Appearing for JEE Advanced 2026

  1. Guessing Answers: Candidates often guess or select options closest to their calculations to save time, but JEE Advanced’s negative marking scheme penalizes such guesses, significantly reducing the final score and impacting rank.

  2. Not Solving Questions on Paper: Attempting to solve complex problems mentally or partially without paper calculations frequently leads to errors, resulting in negative marks, especially in numerical or multi-step questions.

  3. Misreading Questions: Rushing through questions causes candidates to overlook critical details like units or keywords, leading to incorrect answers despite understanding the underlying concepts.

  4. Wasting Time on Difficult Questions: Spending excessive time (e.g., 5–6 minutes) on a single tough question reduces time for solvable ones, disrupting the exam strategy and lowering overall performance.

  5. Experimenting with Unknown Questions: Attempting unfamiliar questions instead of focusing on known or solvable ones wastes valuable time and risks negative marks, derailing a well-planned exam approach.

Common Mistakes to Avoid During JEE Advanced 2026 Preparation


  1. Neglecting the Full Syllabus: Focusing only on high-weightage or favorite topics like Mechanics or Calculus while ignoring areas like Thermal Physics or Inorganic Chemistry leaves gaps in preparation, risking unexpected questions in the exam.

  2. Overloading with Study Resources: Using too many books or online materials simultaneously causes confusion, incomplete coverage, and inefficiency, diluting focus and overwhelming the preparation process.

  3. Inadequate Practice with Past Papers: Not solving enough JEE Advanced past papers (10–15 years) or skipping mock test results in unfamiliarity with the exam’s complex question patterns and time constraints.

  4. Ignoring Error Analysis: Failing to analyze mistakes from mock tests or practice sessions leads to repeated errors, such as conceptual misunderstandings or calculation mistakes, hindering progress.

  5. Poor Time Management in Study Schedule: Studying without a structured plan or spending excessive time on one subject/topic disrupts balanced preparation, leading to burnout or insufficient revision for all subjects.

Additional Tips to Stay on Track During Preparations


1. Create a Strategic Yet Flexible Study Plan


Prepare a realistic timetable that divides your day into focused study blocks for each subject, including dedicated slots for revision, problem-solving, and mock tests. While having structure is crucial, allow flexibility to accommodate tough topics or unexpected delays. A balanced plan helps prevent burnout and ensures complete syllabus coverage with buffer time for deep dives.


2. Focus on Conceptual Understanding, Not Just Problem Quantity


Rather than rushing through hundreds of problems, ensure you deeply understand the theory behind each concept. JEE Advanced tests the application of multiple concepts in a single question, so train your mind to ask “why” and “how” every time you solve something. Build your ability to derive formulas, visualize problems, and solve from first principles.


3. Simulate the Exam Environment Regularly


Take full-length mock tests at least once a week under strict exam conditions (3 hours, no breaks, no distractions). Analyze your performance after every test, review your mistakes, identify weak concepts, and track your progress over time. Simulating the pressure of the actual exam will sharpen your decision-making, stamina, and accuracy.


4. Maintain a Strong Error Log and Revision Cycle


Keep a dedicated notebook or digital tracker for mistakes, note down the concept, type of error (silly, conceptual, or misread), and the correct approach. Revisit this log weekly to prevent repetition of errors. Alongside, follow a structured revision plan to revisit older topics regularly so that they remain fresh until the exam.


5. Take Care of Your Mental and Physical Well-being


Consistency thrives on energy and mental clarity, so prioritize sleep, nutrition, and physical activity. Avoid comparison with others and stay away from unnecessary distractions like excessive social media or study forum stress. Practice mindfulness techniques like journaling, meditation, or even short walks to clear your mind and recharge.

Hello Devanshi

To know the Cutoff of the JEE Mains exam paper for the year 2025, and for previous year, you can visit the link I am attaching below. The link will provide you with the data and help you to improve your performance.

Hello dear candidate,

You can fill your JEE main and advance forms 2026 normally . No, your 11th registration number will not cause any problem.

You will be treated as 12th appearing student in 2026, not as a dropper . You just need to make sure that your CBSE 12th result comes out in 2026 before counselling.

Thank you.

To be eligible for Himachal Pradesh state quota you must have passed atleast two examinations from Himachal pradesh including the 10th and 12th grades. The other criteria are for government employee wards, if the parents have worked there for atleast two years and completed their 10th and 12th from HP.

Hello, Yes, this will almost certainly cause a major problem during your JEE 2026 application.

The National Testing Agency (NTA) is extremely strict about data matching. When you fill out the JEE application, you are required to enter your name, date of birth, and your parents' names exactly as they appear on your 10th-grade marksheet.

The problem will occur during identity verification. The system will try to match the details you entered (from your 10th marksheet) with the data stored in your Aadhaar. When it sees that the father's name does not match, your application will be flagged for a mismatch and will likely be rejected. Even though your name is correct, a mismatch in your father's name is considered a critical data error.

You have time before 2026, so you must get this fixed. The best solution is to get your Aadhaar card corrected. Go to a permanent Aadhaar Seva Kendra (ASK) with your original 10th marksheet and use it as the official proof to update your father's name on your Aadhaar. Do not wait until the JEE registration period begins, as this process can sometimes take time.

Hello, Based on recent JEE Main trends, here are the approximate targets for the OBC-NCL category.

  • For a rank under 20,000 [OBC-NCL]: You should target an overall percentile of 94.5% to 95.5%.
  • For a rank under 10,000 [OBC-NCL]: You should target an overall percentile of 96.5% to 97.5%.

It is difficult to give an exact "marks" target for 2026, as the marks vs. percentile data changes every year and with every single exam shift (depending on its difficulty). However, as a safe estimate, you could aim for 135-145+ marks for the 20k rank and 155-165+ marks for the 10k rank. You should always focus on maximizing your percentile, as that is the more reliable metric.
