Commonly asked questions
Best free mock tests for JEE Mains are previous year question papers. You can also practice NTA mock tests online at nta.ac.in. All mock tests are designed as per JEE Main syllabus and exam pattern.
Usually, in the JEE Mains computer-based exam, questions from maths are presented first, followed by Physics and Chemistry.
But candidates can appear for any section first, as per their preference.
Yes, JEE Main exam has negative marking. 1 mark is deducted for every incorrect answer.
Candidates should take JEE Main mock tests at least once a week. However, in the last month before exam, frequency should be increased to 3 to 4 mock exam per week.
Preparation Strategy for Electrostatics Chapters for JEE Main 2027
Based on the recent trends in Electrostatics questions asked in NTA JEE Mains exam, here are some strategies that candidates should focus on while preparing for this important chapter from the JEE Mains 2027 syllabus:
- Master Class 11 Concepts: Ensure strong command over Vectors (component resolution, dot/cross products), Work-Energy Theorem, and basic Calculus (integration for continuous charge distributions) before going deep, as these mechanics principles directly govern electric field and potential problems.
- Categorise by Core Sub-Units: Divide the topic into four structured pillars:
- Forces & Fields (Coulomb's Law, Superposition principle)
- Gauss’s Law & Flux (Standard symmetries: spherical shells, solid spheres, infinite planes/cylinders)
- Electrostatic Potential & Energy
- Capacitors & Dielectrics (Series/parallel combinations, energy density, dielectric insertions).
- Practice Standard Derivations & Graph Sketching: Practice drawing graphs for conducting and non-conducting geometries (like hollow vs. solid spheres). JEE Main consistently tests graphical interpretation and field variations.
- Solve 2021 to 2026 JEE Main PYQs: Solve at least 150 to 200 previous year questions from this chapter. Group them topic-wise to identify recurring numerical patterns, especially dielectric slab insertions and charge redistribution among connected conductors.
Commonly asked questions
Yes, and in fact, in the JEE Main exam, the weightage of class 11 and topics is almost the same. Candidates have to study topics of both classes 11 and 12 with equal importance.
NO, it is compulsory to attempt all questions in the JEE Main exam. The JEE Main exam has negative marking and candidates must answer only those questions for which they know the correct answer. Students must note that there are no minimum marks in JEE Main that students need to score. Students gets All India Rank based on the marks they secure in exam and gets admission based on that rank.
JEE Main question paper is in English, Hindi and language selected when you filled application form. In total, JEE Main is in 13 languages and you can select any language out of available options. You cannot switch language of question paper during exam.
Chapterwise weightage of class 11 and 12 topics in JEE Main are mentioned below:
- Physics: Current Electricity Waves AC, Magnetism, Laws of Motion Work, Power and Energy.
- Chemistry the high weightage topics are s and p block elements, Coordination compounds, Thermodynamics Gaseous state, Chemical bonding, Atomic structure, Polymers, Environmental Chemistry Organic Chemistry.
- Mathematics, the high weightage topics are Sequence and Series Vectors and 3D, Integral and Differential Calculus, Definite and Indefinite Integral.
Commonly asked questions
Paper 1 has 75 questions where Physics Chemistry and Mathematics, each section has 25 questions. Out of 25 questions, 20 are MCQs and five are numerical value questions. You must answer all 5 numerical value-type questions. All 20 multiple-choice questions are compulsory. Complete all 75 questions in 3 hours.
There are two question types in JEE Main exam. Multiple choice questions and numerical ability questions. In MCQ, every question has 4 options with only 1 correct answer. Select the correct option. In numerical ability question type, no options are there. Solve them and write answer using keyword and mouse.
Questions in JEE Mains exam is a blend of all the topics covered in the syllabus. However, there are some topics that are very much important and should be paid extra attentions while preparing for the exam. The list of important JEE Main topics are
Mathematics
- 3D Geometry
- Vector
- Applications of Derivatives
- Definite Integrals
- Limit, Cnntinuity and Differentiability
Physics
- Heat and Thermodynamics
