Important Chapters For JEE Main 2024: A Guide to the Most Important Topics for Physics, Chemistry, and Mathematics

JEE Main, one of the most challenging exams in the country, continues to test the mettle of aspirants. The exam's difficulty stems from two key factors. Firstly, it attracts a massive number of participants each year, intensifying the competition. Secondly, the syllabus for the exam is vast, covering almost every topic from the NCERT books of classes 11th and 12th.

Understanding the weightage assigned to different chapters is crucial for JEE Main preparation. Not all chapters hold equal importance, and some carry more weight in the exam than others. Consequently, focusing on the key chapters becomes essential to optimise study efforts. While the syllabus has remained largely consistent over the years, certain topics have proven to be constants in the JEE Main question papers.

Since the National Testing Agency (NTA) has been conducting JEE Main from the previous year, the paper's format and topic weightage have retained similarities. This continuity in pattern allows students to gain valuable insights from past papers and identify recurring important topics for JEE Main 2024.

In order to achieve a high score in JEE Main 2024, students should prioritise their proficiency in these significant topics. A strong grasp of these crucial areas can enable students to secure scores exceeding 250+ marks and enhance their chances of success in the exam.

The Most Important Chapters for JEE Main 2024: A Sectional Analysis Physics

The complexity of this section typically spans from moderate to challenging. Scoring well in this section demands a profound understanding of the topics covered. It predominantly comprises numerical questions derived from various chapters, requiring meticulous attention to units when formulating responses. Additionally, the questions delve into a diverse range of laws, further testing the depth of your knowledge.


Over the past years, the easiest section in the JEE Main paper has consistently been this one. The majority of questions in this section are theory-based, and the numerical questions are also straightforward, often solvable using simple formulas. While the questions from physical chemistry are primarily numerical, the rest of the questions from both organic and physical chemistry are based on theory.


Over the years, the Mathematics Section has consistently proven to be the most challenging part of the JEE Main paper. The questions presented in this section demand a substantial amount of time to solve and a strong grasp of concepts. Each question in this segment is of a high level, and none of them rely solely on direct formulas. The crucial topics that dominate this section include calculus, trigonometry, series, and sequence, among others.

The Anatomy of a JEE Main Paper Pattern

Before delving into the crucial topics, students must acquaint themselves with the JEE Main exam's paper pattern, as it plays a pivotal role in their preparation. Familiarity with the paper pattern enables them to devise a well-structured study plan. Below is a concise overview of the JEE Main paper pattern:

  • The examination comprises three sections: Physics, Chemistry, and Mathematics.

  • Each section carries an equal number of questions and holds the same weightage in the overall evaluation.

  • In every section, there are 20 Multiple Choice Questions (MCQs) and 5 Numerical Value Questions (NVQs).

  • The marking scheme for Multiple Choice Questions (MCQs) entails a reward of +4 for each correct answer, a penalty of -1 for each incorrect answer, and 0 marks for unattempted questions. 

  • Similarly, for Numerical Value Questions, a correct response is awarded +4 marks, an incorrect answer incurs a penalty of -1 mark, and leaving the question unattempted results in 0 marks.

  • The question difficulty levels span a wide range, from easy to challenging, assessing the student's comprehensive understanding of the subjects.

  • A total of 3 hours is allotted for completing the entire paper, allowing students ample time to respond thoughtfully and accurately.

  • It's essential to note that the JEE Main is solely conducted in online mode, emphasising the significance of being well-versed in computer-based test-taking strategies.

By being aware of the JEE Main paper pattern, students can optimize their preparation efforts and approach the examination with confidence
