Differential Equations is one of the most important chapters in Mathematics for engineering entrance examinations. Many questions in JEE Main are directly based on standard methods from this chapter, and with the right practice material, students can turn it into a high-scoring area. The uploaded PDF focuses exclusively on Differential Equations and compiles previous year JEE (Main) questions along with their answers and detailed solutions in one place.
I am writing about this PDF because students often search for reliable, exam-oriented practice resources that save time and give clarity. Instead of browsing multiple books or websites, this single document provides a structured collection of real JEE questions, an answer key, and worked explanations. Knowing what type of questions are repeatedly asked and how they are solved can significantly improve both confidence and accuracy.
What This PDF Contains
The PDF is designed as a chapter-wise practice booklet for Differential Equations. It starts with the syllabus, followed by multiple-choice questions taken from different JEE Main sessions, and then provides an answer key and detailed solutions.
Students will find:
- Official syllabus topics for Differential Equations
- JEE Main previous year MCQs
- Complete answer key
- Step-by-step solutions with hints and methods
This structure makes the PDF useful for both learning and revision.
Syllabus Topics Covered
The document clearly lists the areas included under Differential Equations. These match the JEE Main Mathematics syllabus and include:
- Ordinary differential equations
- Order and degree of differential equations
- Formation of differential equations
- Solution by separation of variables
- Homogeneous differential equations
- Linear differential equations of the form dy/dx + p(x)y = q(x)
These topics form the foundation for most exam questions from this chapter.
JEE Main Previous Year Questions Included
The PDF contains a large set of multiple-choice questions collected from JEE Main papers of recent years, including different shifts from 2021, 2022, and 2023.
Most questions are based on:
- Solving linear differential equations using integrating factor
- Using substitution methods such as y = vx or y² = u
- Applying initial conditions to find constants
- Finding particular solutions
- Application-based problems involving maxima, minima, and curves
Practising these questions gives students a clear idea of exam difficulty and pattern.
Answer Key Section
After the questions, the PDF provides a consolidated answer key where each question number is matched with the correct option.
This helps students quickly verify their answers after practice and identify weak areas.

Detailed Solutions and Explanations
The solutions section explains each problem step by step. Important steps such as converting equations into linear form, calculating integrating factors, performing substitutions, and applying initial conditions are shown clearly.
Hints are also provided for several questions, guiding students on the best method to use. This makes the PDF especially helpful for self-study.
How This PDF Helps in JEE Preparation
This PDF can be used as:
- A chapter-wise practice resource
- A revision booklet before tests
- A tool to understand commonly asked question types
- A guide to improve problem-solving speed and accuracy
Since all questions are from actual JEE Main exams, practising them builds real exam readiness.
Suggested Study Approach
Students can follow this simple method:
- Revise theory of Differential Equations
- Attempt a set of MCQs from the PDF
- Check answers using the answer key
- Study solutions for incorrect questions
- Make short notes of formulas and methods
Repeating this regularly will strengthen concepts and confidence.
Who Should Use This PDF
- JEE Main aspirants
- Class 11 and Class 12 students
- Students preparing for other engineering entrance exams
- Anyone who wants strong conceptual clarity in Differential Equations
