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.

With a BC-E category certificate, EWS certificate, and Telangana home-state quota, your chances of getting admission to AIML or related CSE branches in CBIT, VNR VJIET, or similar top private colleges in Telangana depend mainly on your JEE Main percentile and the TS EAMCET counselling process, because these colleges fill seats through both TS EAMCET ranks and JEE Main scores (Category-B seats).

For Category-A seats (through TS EAMCET), JEE Main percentile is not considered. Admission is purely based on your TS EAMCET rank, reservation category, gender, and home-state status. CBIT and VNR are highly competitive, especially for AIML, CSE, and IT branches, so you generally need a very strong TS EAMCET rank (usually within a few thousand for BC-E candidates, sometimes slightly relaxed for girls).

For Category-B seats (JEE Main quota), JEE Main percentile matters. Based on recent trends, to have a realistic chance:

  • For CBIT (AIML / CSE / IT), a JEE Main percentile of around 95+ is usually expected, even for reserved categories, because Category-B seats are limited and competition is high.

  • For VNR VJIET (AIML / CSE / IT), candidates with 92–95 percentile sometimes have chances, depending on availability and the specific branch.

  • If your percentile is below 90, getting AIML or core CSE in CBIT or VNR becomes difficult, but you may still have chances in slightly lower-demand branches (like ECE, EEE, or emerging specialisations) or in other good private colleges affiliated with JNTU or autonomous institutions.

Your BC-E and EWS certificates do help mainly in TS EAMCET counselling (Category-A seats), not significantly in Category-B (JEE Main) admissions, where merit largely dominates. Home-state status is already assumed for these colleges, so there is no extra advantage beyond eligibility.

In summary, if your JEE Main percentile is 95 or above, you can reasonably target AIML/CSE in VNR and possibly CBIT through Category-B. If it is 90–94, VNR or related branches are more realistic than CBIT. Below that, it is better to focus on TS EAMCET performance or consider other reputed Telangana colleges offering AIML. If you want, you can share your exact JEE Main percentile and TS EAMCET rank, and I can give you a more precise college- and branch-wise estimate.
