Preparing for JEE Mains and JEE Advanced requires a lot of hard work, determination and planning. To put it simply, you need to harness a certain amount of passion to crack the exam in the first attempt itself. With 1.2 million students taking a shot at it, you have to be at your imperial best to make it through. Time management, planning and being smart in your preparations is the key to success. Hence, you need to be clear about the amount of time you need to dedicate to the JEE syllabus of class 11th and 12th respectively, according to their weightage.

Class 11 syllabus has slightly more weightage in JEE syllabus

From past records, we can say that the class 11 syllabus has slightly more weightage than class 12. There have been years where students who studied the class 11th syllabus more comprehensive had a slight edge over others. 55% of the questions coming from that syllabus. Conversely, there have also been some years when both held the same weightage. Regardless of the that, one thing you need to keep in mind that: You need to be completely thorough with the class 11th syllabus to do well, while also being confident about your knowledge of the syllabus of class 12th as well. While the class 11th is the foundation upon which you build your goals, class 12th gives you the finishing touches. Therefore, both are equally important in terms of knowing the study material.

Changes in the pattern of questions for the exams

With the NTA (National Testing Agency) laying out fresh changes in the pattern of questions, there have been a lot of murmurs about how it may affect the weightage of the JEE syllabus from both classes. The changes brought about by NTA have been proportional to all three subjects – Physics, Chemistry and Mathematics. While the earlier pattern had 30 questions from each subject, adding up to 90 questions (360 marks) in total, the new pattern has 25 questions from each subject to make it 75 questions (300 marks) in total. For each subject, out of the 25, 20 will be MCQs and the remaining 5 will be numerical based.  It simply implies that the questions now focus on an in-depth knowledge because the number of questions have been decreased, with the allotted time of 3 hours to complete the exam remaining the same. 

To get a better understanding of how to prioritise the weightage, let us take a look at an in-depth analysis of the topics covered in the 2019 JEE Mains Exam.

JEE Syllabus - class 11 vs class 12 Kunduz

Important chapters in JEE syllabus that you cannot miss!


The following chapters are very important:
  • Class 11 – Waves, Simple Harmonic Motion, Rotational Motion, Newton’s Law of Motion and Units of Dimensions. 
  • Class 12 – Electrostatics, Magnetism, Current Electricity, Optics and Modern Physics.


In Chemistry, all chapters are equally important because in most cases, there is at least one question from each chapter. While the Class 11 syllabus gives you a strong base, Class 12 syllabus gives you an in-depth knowledge about the subject. 


The following chapters are very important:
  • Class 11 – Coordinate Geometry, Permutations & Combinations, Probability, Complex Numbers, Progressions and Binomial Theorem.
  • Class 12 – Matrices, Calculus, Vectors and 3D Geometry. 
After this in-depth analysis of the JEE Mains exam of last year, you must have noticed how noticed how the syllabus of class 11 has slightly more weightage in terms of the number of questions. Moreover, only when you are clear with the concepts of class 11 can you go ahead and master the syllabus of class 12. Therefore, it is clear that you need to focus on class 11 slightly more to score well in JEE Mains. You can click here to download Kunduz!
