Weightage of Class 11th & 12th subjects in JEE Main and JEE Advanced exam

Weightage of Class 11th & 12th subjects in JEE Main and JEE Advanced exam


JEE is one of the most competitive examinations in the country. Every year, about 1.2 million candidates appear for the JEE Main exam, out of which, a fraction of students qualify to appear for the JEE Advanced exam. While preparing for an examination, in which the level of competition is sky-high, and the syllabus comprises of that of class 11 and 12, you would certainly want to know the weightage of syllabus of class 11 and 12 in JEE.

Remember that JEE is highly competitive and the paper-setters are very clever. They can ask the questions from the topics that many students tend to ignore. Hence, for obtaining a good rank in JEE, it is advisable not to keep the weightage of the topics in mind while studying them. Study each and every topic with utmost seriousness and dedication. The only way through which you can ace this exam is by preparing for the worst. However, to satisfy your curiosity, it makes sense for you to know the general trends across the various JEE papers. Hence, in this article, we will discuss about the class 11th vs class 12th weightage in JEE.

Before delving into the statistics and our analysis, it is important to take into account that a majority of the questions that appear in JEE, involve a mix of concepts. Hence, a single question can involve concepts from both class 11 and class 12. In this case, the most important topic is considered and the primary one and the marks distribution would vary accordingly.

Overall Analysis

In this section, we will discuss about the overall weightage of topics of class 11 and 12 spread across all the three subjects - Physics, Chemistry, and Mathematics, in both JEE Main and JEE Advanced.

Generally, in JEE Main, the weightage of syllabus of both class 11 and class 12 is 50% each. There are certain topics that are specific to JEE Main and are absent from JEE Advanced syllabus. These topics include Semiconductors, Electromagnetic waves and communication, Optical instruments, and Damped SHM in Physics; F-Block elements, Environmental chemistry, and Biomolecules in Chemistry; and Statistics in Mathematics. It is very likely to encounter some problems from these topics. Hence, you should take these topics seriously if you want to ace the JEE Main.

Subject-wise Analysis

In this section, we will discuss about the relative weightage of syllabus of class 11 and class 12 in each subject. We will also discuss about some important topics from class 11 and class 12 that should not be ignored at all since they have a great importance when it comes to JEE questions.

Physics

In Physics, the weightage of syllabus of class 11 and 12 is almost equal -- it is around 50% for each. Some important chapters of Physics in class 11 include Waves, Simple Harmonic Motion, Units and Dimensions, Rotational Motion, and Newton’s Laws of Motion. The class 12 Physics topics that carry heavy weightage in JEE include Electrostatics, Magnetism, Current Electricity, Optics, Modern Physics.

Chemistry

In JEE chemistry, generally, the weightage of class 12 syllabus is more than that of class 11. Generally, the weightage of class 11 chemistry syllabus in JEE is around 30% to 40%. Many topics that are taught in class 11 are the basic ones and serve as a foundation for deeper understanding of many class 12 topics. So, even though the weightage of class 11 syllabus is slightly on the lower side, the topics taught in class 11 should not be ignored or taken for granted.

Some topics of class 11 chemistry that are quite important from the point of view of JEE questions are Chemical Bonding, Chemical Equilibrium, Gaseous State, Atomic Structure, General Organic Chemistry, and Stoichiometry. As far as class 12 chemistry syllabus is considered, it is equally likely to find a question from any of those chapters in JEE.

Mathematics

Generally, the weightage of topics of class 11 mathematics is 40% to 50% in JEE. Some of the important topics of class 11 mathematics, that are important from the perspective of JEE questions are Coordinate Geometry, Permutations and Combinations, Probability, Complex Numbers, Binomial Theorem, and Progressions. Matrices, Calculus, Vectors and Three-dimensional Geometry are some of the class 12 mathematics topics that are important from JEE perspective.

Conclusion

JEE is a very tough competition, where the difference of even 1 mark can cause a lot of damage to one’s rank. Hence, it is important to be equally proficient in all the topics, both from class 11 and class 12. Even though it may seem like that a majority of JEE questions are from class 11 syllabus, however, you must notice that JEE questions generally involve a mix several concepts, and hence, you should be comfortable with all the concepts involved so as to apply them in a single question. Generally, in class 11, foundations of several advanced concepts are laid. Hence, you should pay equal attention to the syllabus of class 11 and 12, both.
