The uploaded PDF contains the Mathematics section of the JEE Main 2024 question paper, conducted on 27 January, Shift 1. It includes Section A multiple-choice questions along with official exam instructions and marking scheme. The questions test a wide range of mathematical concepts, focusing on logical thinking, formula application, and problem-solving speed rather than lengthy calculations.
I am writing about this paper because analysing an actual JEE Main Mathematics paper helps students understand how questions are framed in the exam. Instead of relying on assumptions or coaching predictions, this paper shows exactly which chapters were tested and how deeply concepts were applied in a real exam setting.
Structure of the Mathematics Paper
As mentioned in the PDF, the Mathematics paper is divided into two sections. Section A consists of 20 multiple-choice questions, each carrying 4 marks, with a negative marking of 1 mark for every incorrect answer. Section B consists of 10 numerical value type questions, out of which candidates must attempt any five. Each numerical question carries 4 marks with no negative marking.
This structure follows the standard JEE Main pattern and rewards both accuracy and smart question selection.
Coordinate Geometry and Vectors
Several questions in Section A are based on coordinate geometry. One question involves finding the orthocentre of a triangle formed by three given points and then evaluating definite integrals using the obtained coordinates. This question combines geometry with calculus, testing multi-topic application.
Another coordinate geometry question focuses on distance of a point from a line measured along another line, requiring understanding of direction ratios and shortest distance concepts in three-dimensional geometry.

Calculus-Based Questions
Calculus appears through definite integrals and differential equations. One question involves evaluating integrals with sine functions and limits expressed using variables, testing comfort with trigonometric integration.
Another calculus question involves first-order differential equations, where solutions of two differential equations are compared using given initial conditions. The question then asks for the value of time at which both solutions become equal, testing conceptual clarity rather than heavy calculation.
Circles and Straight Lines
A geometry question involves four points lying on a circle, where the value of a parameter is to be determined. This tests understanding of the general equation of a circle and conditions for concyclic points.
Another problem focuses on straight lines in the first quadrant, where a line segment is trisected by two lines passing through the origin. Students are required to find the tangent of the angle between those lines, testing ratio concepts and slope interpretation.
Statistics and Data Interpretation
The paper also includes a question from statistics, where mean and sum of squares of observations are given. Using this data, students are asked to find the standard deviation of the observations. This is a direct but concept-based question that rewards familiarity with standard deviation formulas.
Level and Nature of Questions
Based on the questions shown in the PDF, the Mathematics paper in Shift 1 is moderate in difficulty. The questions are not extremely lengthy, but many require combining concepts from different chapters. Speed, accuracy, and strong fundamentals are clearly more important than memorising tricks.
The paper maintains a good balance between algebra, calculus, coordinate geometry, and statistics.
What Students Can Learn from This Paper
From this paper, it is clear that:
- Multi-concept questions are common
- Coordinate geometry remains a high-weightage area
- Calculus questions focus on understanding rather than long solutions
- Formula-based chapters like statistics are scoring if concepts are clear
Practising such papers helps students improve exam temperament and time management.
