CBSE Class 12 Mathematics is the foundation for calculating complex engineering and scientific problems. In the JEE Main 2022 examination, almost every question was solely based on mathematical formulae and applications. This section needs to be practised very well to obtain the best marks. There are a handful of chapters included in the JEE Mathematics.
Moreover, unlike Physics and Chemistry, there is nothing like the least important or most important topics based on the level of importance to cover in mathematics. Because all the topics are interlinked to one another, the JEE aspirants must study all the chapters and every concept included in them. Also, they cannot skip between chapters since all are equally important.
In this informative article, let us learn the topics and how to schedule and study them to achieve good grades in the examination.

JEE Mathematics Syllabus
Most topics that appear on JEE Main are from CBSE Class 12. The students should be able to differentiate between each topic and know what the formulae are to solve the problems given in these topics. There are five most common chapters asked in previous years’ JEE examinations. They are as follows:
- Coordinate Geometry
- 3D Geometry and Vectors
Let us have a wide look at all of them in detail.
Due to the level of difficulty of this chapter, it is very crucial for both JEE Main and JEE Advanced examinations. This chapter has a wide variety of formulae and concepts to cover by the students. It is possible that in all the engineering entrance exams, a few questions from this chapter are asked without any denial.
This unit plays a key role in understanding all the other concepts of Mathematics, and the students will not have to worry about the examination if they are thorough with this one. This chapter requires strong development and understanding to achieve higher grades. Therefore, it is essential to have a neat preparation in this unit. The following are some of the important subtopics included in this chapter:
- Differentiability and Continuity
- Relationship between Differentiability and Continuity
- Definite Integrals
- Integration by Parts
- Properties of Definite Integrals
- Rate Measurements
- Maxima and Minima
- Tangents and Normal
- Area under curves
- Differentiation Equations
A coordinate system is considered a system capable of utilising one or more coordinates or numbers. It illustrates the geometrical elements and position of points on a manifold, which is a Euclidean Space, uniquely. The basic purpose of this unit in JEE Main is to make the students understand some of the geometrical shapes like a parabola, hyperbola, ellipse, circle, etc.
The questions asked from this unit are primarily of application of different formulae discussed in this chapter, which makes it very interesting and engaging for the students. Due to this, they can score higher marks in this chapter than any others in JEE Maths. It is easy to obtain the maximum marks from this particular unit.
The aspirants of Mathematics should have to focus more on the following topics to attain higher marks:
- Straight lines
Among them, Circles and Straight lines are the most fundamental ones.
3D Geometry and Vectors
This unit in Class 12 Mathematics is a bit complex since most of the topics in this chapter are conceptual. In JEE 2022, the weightage given to this chapter compared to the Co-ordinate Geometry is somewhat similar. This chapter includes some parts of Geometry and Complex numbers in it.
The students of JEE Mathematics must understand specific complex vector concepts and 3D Geometry to attain excellent grades from questions asked in this unit. So, a proper understanding of the topics mentioned above is a must. The JEE aspirants have to try developing a strong foundation on the basics and concentrate more on this chapter through visual understanding.
Algebra plays a vital role in all the mathematical entrance and final examinations. The usage of this unit in all those examinations is humongous. Algebra is an interesting unit covering certain topics, namely Matrices, Logarithms, Determinants, and Quadratic Equations. All these have been very popular among students since primary school to understand the concepts very easily. For some students, it is even their favourite unit in Mathematics.
Moreover, in both JEE Main and JEE Advanced exams, questions on the topic of Complex numbers merged with the Vectors have been asked continuously. In the JEE Advanced exam, the aspirants can expect a passage-type question from determinants and matrices. It might be one of the easiest to answer.
In addition to this, it is possible to have questions from Permutations and Combinations. Some of the Formula-based questions are usually asked from Series and Sequence and Binomial Theorem. Therefore, by practising regularly, students can easily avoid silly mistakes, which open up a gateway to obtaining maximum marks in all these topics.
Trigonometry is a very fundamental topic for the JEE Main examination. The following are the three most imperative topics the JEE aspirants should have their focus on:
- Trigonometric functions
- Inverse Trigonometry
- Trigonometric ratios
Moreover, for the JEE Maths aspirants to benefit from this chapter, they should have a firm understanding of all the basic concepts since a good amount of questions have been asked from this particular unit.
Therefore, memorising all these concepts and trigonometric formulae would play a key role in scoring well in this unit. Apart from that, it is also equally important to learn their graphs and substitutions.
Maths section in JEE Main 2019
The JEE Main 2019 examination level was set on moderate because it contains many questions that were neither difficult nor easy to answer. This section consists of more calculations with the candidates found hard to manage within the given time frame. It took a longer time than usual.
Furthermore, while breaking up the no. of questions and from which topics they were from:
- Algebra – 9 questions
- Calculus – 9 questions
- Coordinate geometry- 8 questions
- Probability – 4 questions
- Statistics – 4 questions
- Mathematical reasoning – 4 questions
Based on difficulty levels, 13 questions were easy and took less time to answer. Meanwhile, the other 13 questions were moderate and took a little more time to finish. Furthermore, four questions were difficult, and candidates took more time to accomplish them.
To be more precise with the topics and concepts that were asked in the JEE Main 2019 Examination under the Mathematics section, let us have a look at the following tabulation:
|Topics||No. of questions||Weightage of marks|
|Limits, Differentiability and Continuity||3||12|
|Complex numbers and Quadratic Equation||2||8|
|Matrices and Determinants||2||8|
|Probability and Statistics||2||8|
|Statics and Dynamics||1||4|
|Binomial Theorem and its Application||1||4|
|Sequences and Series||1||4|
|Sets, Function and Relation||1||4|
|Permutations and Combinations||1||4|
So, from this, the important chapters covered in the JEE Main 2019 question paper are:
- Probability and Statistics
- Application of Derivatives
- Binomial Theorem
- 3D Geometry
- Matrices and Determinants
- Complex Numbers
Maths section in JEE Main 2018
The level of the Maths section in JEE 2018 was difficult. The candidates felt they needed more time to do the calculations because they were very lengthy, and the time given was not enough. In the exam, 20 questions were asked from the syllabus of 11th grade, whereas ten were from the 12th grade. Therefore, there were 30 questions, out of which ten were easy, 13 were moderate, and seven were difficult.
The following table provides the details of important questions that were asked, with the distribution of marks.
|Important topics||Distribution of marks|
