How to Score 99 Percentile in JEE Mains?

How To Score 99 Percentile in JEE Mains: The Joint Entrance Examination Main (JEE Main) is a national-level engineering entrance exam conducted by the National Testing Agency (NTA). It is held twice every year, usually in January and April. The exam helps students get admission into top engineering colleges such as NITs, IIITs, and other Government Funded Technical Institutes (GFTIs). Moreover, students who clear JEE Main with good percentile are allowed to sit for JEE Advanced, which is required for admission to IITs.

The JEE Main exam is based on the Class 11 and 12 syllabus of Physics, Chemistry, and Mathematics. The paper is conducted in a computer-based format, and it consists of 90 questions, out of which 75 questions must be attempted. These are spread across the three subjects with each subject having 20 MCQs and 10 numerical questions, from which students have to attempt 5 numerical ones. The paper is out of 300 marks, and each correct answer gives you +4 marks while each wrong MCQ deducts 1 mark.

Scoring a 99 percentile in JEE Mains means securing a very high rank among lakhs of students. Generally, this percentile lies within the top 10,000 ranks, and students scoring around 180–190 marks fall into this category. In this guide, we will explain how to reach this level step-by-step in a very easy and understandable way.

JEE Main Preparation Tips

1. Build a Strong Foundation with NCERT First

Before moving to advanced books, make sure your basics are clear. NCERT books are the base for all three subjects, especially Chemistry. Many questions in JEE Mains are directly picked from NCERT, especially in Organic and Inorganic Chemistry.

If you skip NCERT and jump directly to advanced books, you might face difficulty in understanding advanced problems. You need to know basic definitions, laws, and formulas properly to solve MCQs and numerical questions correctly.

• Read NCERT Class 11 and 12 line by line for Chemistry.

• Make short notes for each topic in Physics and Chemistry.

• Understand concepts, don’t just memorise without meaning.

2. Follow a Balanced Subject-Wise Approach

To score well, give equal time to Physics, Chemistry, and Mathematics. Many students tend to focus more on Maths or ignore Chemistry, but all three subjects carry the same weight. Try to do all three subjects in your daily routine. If you study only one subject for too long, it can cause boredom and imbalance in preparation.

• Study all 3 subjects every day, even for a short time.

• Rotate between concept learning, problem-solving, and revision.

• Don’t ignore your weak subject, spend more time on it instead.

3. Solve Previous Year Questions and Mock Tests

Solving previous year JEE Mains questions is one of the smartest ways to prepare. These questions show what types of problems are asked again and again. You also learn which chapters are important. After solving a paper, you should always go back and see your mistakes.

Mock tests also help in improving your speed and accuracy. They train you to sit for 3 hours with full focus. But just giving mock tests is not enough. You must analyse your performance after each test.

• Solve at least 5 years’ worth of PYQs for each subject.

• Take mock tests weekly; increase the number in the last 2 months.

• Use test series from trusted platforms like NTA Abhyas or PW.

4. Revise Regularly and Make Quick Notes

Revision is the most important part of your study plan. Whatever you study today should be revised again after a few days, or you will forget it. The human brain forgets things quickly if not revised.

You should create small revision notes, especially for formulas, important reactions, and shortcuts. These can be revised quickly just before tests or the actual exam.

• Make formula sheets for Physics and Maths.

• For Chemistry, make reaction charts and NCERT summary pages.

• Use weekends for full chapter revisions instead of new topics.

5. Work on Time Management and Accuracy

Even if you know all the answers, you still need to manage your time well in the actual paper. Each question should be solved within 2 minutes. Also, you should avoid silly mistakes. That’s why you need daily practice and real-time mock test experience.

To improve your speed, use timers while solving MCQs. Start with untimed practice, then move to timed sessions. Also, don’t try to attempt all questions, focus more on accuracy.

• Practice solving 75 questions in 3 hours at home.

• Use OMR sheets or online practice platforms.

• Skip questions you’re unsure about to avoid negative marking.
