Commonly asked questions
Clearing the JEE Main exam in first attempt is not a difficult task. Several students clear JEE Main while in class 12. One thing that makes it easy to clear JEE Main with class 12 is that students are in regular touch of most JEE syllabus. To score good marks in JEE Main in the first attempt, it is advised that you study class 11 and 12 topics thoroughly, clear all the concepts and solve mock test papers. Also, NCERT books which you study in class 11 and 12 are the best books for JEE Main preparation. Students must study NCERT properly and solve all the questions in the book and do not memorize the concepts as some students do rather understand the concepts.
The time period required to complete the JEE Main preparation depends mainly on the students. Every student has their own pace of study. Ideally, 6-month time is good enough to complete the JEE Main preparation. Students who have started preparing from class 11 or 12 can easily prepare for JEE Main in 6 months considering the topics of JEE syllabus have already been studied in classes 11 and 12.
JEE Main preparation is most effective with classes 11 and 12 as almost 90-95 percent of topics are similar in both exams. This way students can easily complete the entire JEE Main syllabus as well as the syllabus of classes 11 and 12. After the board exams, students get 1-2 months' time where they can focus entirely on JEE Main. Students who have started late for the JEE Main exam can make a 6-month plan where in the first three months they have to focus on revising the syllabus studied in classes 11 and 12. In the next two months focus on solving questions of JEE Main and analyzing the mistakes being made, if any. The last month should be focused on solving mock tests and JEE Main previous year question papers.
Candidates can check JoSAA opening and closing ranks on the official website. They have to enter the details asked to check the list of courses and colleges based on the OR and CR of each counselling round.

A score of 70 marks in JEE Mains is considered average to below-average for General category students. This corresponds to a percentile around 88 to 91.
The difficulty level of JEE Main exam is a little high than the class 12 board exams. Students who are studying in class 12 can score good marks in JEE Main by studying a little extra for the JEE. Students who have studied NCERT textbooks of Physics Chemistry and Mathematics thoroughly can get good marks. The joint Entrance Examination, popularly known as JEE Main is for admission into NITs, IIITs, and GFTIs for B.Tech and architecture courses in India.
JEE Main difficulty level is similar to class 12 board exams. Syllabus of JEE Main is similar to class 11 and 12 syllabus. The questions asked in exam are tricky and need an in-depth understanding of subjects. They need to have conceptual understanding of every topic to score well in exam. Those who study NCERT can get a decent score in JEE Mains.

Commonly asked questions
While NCERT books are good to begin the JEE Mains preparation, students should not study only NCERT. As JEE Mains exam is known to test candidates conceptual and analytical skills, and to have all the knowledge that would help in achieving a good score, candidates must also refer other study materials as recommended by teachers to prepae for the exam.
Students who are in class 12 and would also be appearing in JEE Mains exam mostly find it difficult to manage both their class/school and JEE studies. However, all these students have an advantage over others/droppers aspirants as there are many common topics in class 12 and JEE.
To benefit, they must identify all the topics that are common and study those first. Secondly, cover the topics that have more weightage in class 12 and complete them. Before a few days of JEE Mains, study specifically for JEE. This way, they can manage both class 12 and JEE efficiently.
The best way to handle tough topics in any subject is to study the concepts of that particular topic. The conceptual understanding of any topic gives us the clarity to solve theoretical as well as numerical questions from that topic. NCERT text books are the best material to understand the core concepts.
How to Score 200+ in JEE Main 2027 with High Weightage Chapters
Scoring 200+ marks in JEE Main 2027 secures a 99+ percentile, opening doors to top branches at premier NITs.
The strategy is simple - mastering high-yield chapters (60% to 70% of the exam) with 85 to 90% accuracy across 75 total questions.
- Chemistry (75 to 80 Marks in 40 mins): Focus on Coordination Compounds, Chemical Bonding, GOC, Aldehydes & Ketones, Solutions, and Electrochemistry.
- Physics (65 to 70 Marks in 55 mins): Prioritise Modern Physics, Semiconductors, Current Electricity, Optics, Work-Energy, and Thermodynamics.
- Mathematics (55 to 60 Marks in 65 mins): Target Vectors & 3D Geometry, Matrices & Determinants, Statistics, Sequence & Series, and Definite Integrals.
Tips:
- Master NCERT: Memorise Inorganic reactions and physical chemistry definitions line-by-line.
- Solve Chapter-Wise PYQs: Complete all previous 5 years JEE Main shift questions from 2021 to 2026 to master recurring patterns.
- Filter Questions: In Math, solve direct algebraic/vector questions first and skip calculation-heavy problems.
- Maintain Accuracy: Attempt 52 to 56 questions you are completely confident about rather than blind guessing to eliminate negative marking.

How to Use High Weightage Chapters for JEE Mains 2027 Preparation
In JEE Main, covering all units and topics is important. Just because a chapter carried low weightage up until now does not mean it will continue to have lower weightage in upcoming exams too. The tables can turn at any time in the JEE Main exam. Therefore, candidates must use the tips below to utilise the high weightage topics for JEE Mains 2027 preparation keeping in mind all topics from the JEE Mains 2027 syllabus are covered.
Align Time Allocation with High JEE Weightage Chapters
-
Allocate roughly 60% of weekly practice time to chapters with the highest weightage in Maths, Physics and Chemistry.
-
Avoid spending 3 weeks on a single low-weightage topic while leaving high-frequency chapters rushed near exam time.
Follow the "Weightage vs. Important" Rule
-
Never skip foundational low-weightage topics if high-weightage chapters depend on them.
-
Example: Kinematics & Newton's Laws may yield only 1 to 2 direct questions each, but mastering them is mandatory before tackling Rotational Motion, Work-Energy, or Electrostatics.
-
Example: General Organic Chemistry (GOC) is the prerequisite for all Class 12 high-weightage Organic reaction mechanisms.
Use Weightage to Decide PYQ Practice Volume
-
High Weightage Chapter PYQs: Solve the last 5 years of JEE Main question papers. Aim for 80 to 120 PYQs per high weightage chapter.
-
Medium or Low Weightage PYQs: Solve 30 to 50 standard PYQs to capture repeating formulas and standard question templates.
Common Mistakes to Avoid
-
Ignoring topics: Never leave any chapter completely untouched. If time is less, complete NCERT theory and direct formula applications even for low-weightage chapters.
-
Over-Practicing One Topic: Spending months solving olympiad-level mechanics problems while neglecting Inorganic Chemistry or 3D Geometry leads to severe mark loss.
