Preparing for JEE Main can feel overwhelming. With changing guidelines, new exam patterns, and pressure to perform, students often struggle to find reliable answers to their most common doubts. To make your journey smoother, we have compiled the Top 25 Frequently Asked Questions About JEE Main—answered in simple and clear language by expert mentors.
Whether you’re a first-time aspirant, a dropper, or still confused about strategy, this guide will help you get clarity, confidence, and direction.
JEE Main (Joint Entrance Examination – Main) is a national-level engineering entrance test conducted by the National Testing Agency (NTA). It is the primary gateway for admission to NITs, IIITs, GFTIs, and acts as the qualifying examination for JEE Advanced, which leads to IIT admission.
Students who have completed or are appearing in Class 12 (Science stream with PCM) are eligible. There is no minimum percentage required to appear, but certain marks may be needed for college admission.
No — NTA has removed the age limit. Students must simply meet the educational qualification criteria.
A candidate can appear in both sessions (January and April) in the same year. The best score will be considered for ranking and admission.
| Question Type | Correct Answer | Incorrect Answer | Unattempted |
| MCQ | +4 | –1 | 0 |
| Numerical Value | +4 | –0 (no negative) | 0 |
Yes. Attempting both sessions is optional — but experts recommend attempting both to improve your percentile.
Percentile score reflects the relative performance of a student, not the raw marks. It indicates how many candidates scored below you.
Generally:
| Target College | Safe Percentile |
| Top NITs (CSE) | 98.5–99.8 |
| Good NITs | 96–98 |
| Other NITs/GFTIs | 92–96 |
Cut-offs vary every year based on difficulty, number of candidates, and seat availability.
Begin with a well-structured plan:
NCERT is excellent for Chemistry and basics, but for JEE-level problems, additional practice from reference books and mock tests is required.
Selecting the right books is extremely important for effective JEE Main preparation. While there are many options available, using a balanced combination of concept-building books + practice books works best.
Below is a recommended book list, commonly used by successful JEE aspirants:
| Subject | Recommended Books | Purpose |
|---|---|---|
| Physics | Concepts of Physics by H.C. Verma, DC Pandey Series | Builds strong concepts and provides quality numerical practice |
| Chemistry | NCERT (must-read), O.P. Tandon (Physical/Inorganic), MS Chauhan (Organic) | NCERT forms the base, while reference books help with deeper understanding and question practice |
| Mathematics | RD Sharma (Objective), Cengage Series | Ideal for concept clarity, variety of problems, and exam-level question practice |
Note: Students enrolled in ALLEN Overseas can prioritize the ALLEN study material, modules, and test series, as they already cover NCERT, past years’ questions, and exam-focused practice.
Mock tests are extremely important. They help you improve:
At least 1 full test per week, and in the final 2 months, increase to 3–4 tests per week.
Focus on:
The goal is to reduce mistakes, not just complete tests.
Yes — many top rankers are droppers. With consistent revision, disciplined routine, and proper guidance, cracking JEE Main is absolutely achievable.
Ideal approach:
Revision is the heart of preparation. Without revision, retention drops and accuracy suffers.
Both are important. Understand the concept first, then solve problems of varying difficulty to strengthen application.
Quality matters more than time. On average:
Consistency beats motivation.
Always check the official NTA guidelines before the exam.
Based on your percentile, you can:
A low score doesn’t define your potential. Analyse mistakes, improve weak areas, and prepare with renewed strategy for the next attempt.
The journey to JEE Main is challenging, but with the right guidance, consistent practice, and a calm mindset, success is within reach. Every doubt you clear and every step you take brings you closer to your engineering dream.
