Why Knowing Important Chapters Matters
Many students try to complete the entire syllabus but end up revising nothing properly. Knowing priority chapters helps you:
Score more with focused preparation
Improve accuracy and speed
Build confidence before the exam
Use revision time efficiently
A smart preparation plan always begins with high-weightage topics.
Most Important Topics Inside Each Chapter
Let’s break down what to study inside major chapters.
Calculus
Important topics include:
Limits and continuity
Differentiation techniques
Application of derivatives
Indefinite and definite integration
Area under curves
Differential equations
Differential calculus alone can contribute 4–6 questions in some papers.
Coordinate Geometry
Key topics:
Straight line
Circle
Parabola
Ellipse
Hyperbola
Coordinate geometry is often one of the highest-weightage units in JEE Main.
Algebra
Important topics:
Complex numbers
Quadratic equations
Sequence and series
Binomial theorem
Matrices and determinants
Algebra consistently contributes a large portion of questions every year.
Vector Algebra and 3D Geometry
Key topics:
Direction ratios
Equation of line and plane
Vector products
Vectors and 3D geometry questions are usually straightforward and scoring.
Probability and Statistics
Important topics:
Mean, median, mode
Standard deviation
Probability theorems
Bayes theorem
These questions are often formula-based and scoring.
Subject-Wise Distribution Trend
Recent data shows approximate distribution:
Calculus – about 30–37%
Algebra – about 33–39%
Geometry (2D + 3D) – about 25–27%
Trigonometry – small but consistent portion
This confirms that mastering Calculus and Algebra is essential.
Smart Preparation Strategy for JEE Main Maths
Step 1: Start With Basics
Before jumping into advanced problems:
Revise NCERT formulas
Understand concepts clearly
Practice basic questions
Step 2: Focus on High Weightage Chapters
Prioritize:
Calculus
Algebra
Coordinate Geometry
These alone can help you attempt a majority of questions.
Step 3: Practice Previous Year Questions
Previous year papers help you:
Understand difficulty level
Identify repeated patterns
Improve speed
Step 4: Revision Strategy
Revision is critical:
Maintain formula notebook
Revise weekly
Solve mixed question sets
Time Allocation Strategy
If you have 6 months:
2 months – Algebra + Calculus basics
2 months – Advanced practice + Geometry
1 month – Mock tests
1 month – Revision
If less time remains, prioritize:
Calculus
Matrices
Probability
Coordinate Geometry
Common Mistakes Students Make
Ignoring easy scoring chapters
Memorizing formulas without understanding
Not solving previous year questions
Avoiding mock tests
Leaving revision for the last month
Avoiding these mistakes can significantly improve your score.
How Many Chapters Are Enough to Score Well?
Many experts and students observe that mastering core chapters can cover a large portion of the paper.
A popular student discussion summarized that topics like calculus, sequence and series, coordinate geometry, vectors, and differential equations form a large share of questions each year.
This doesn’t mean you should skip the syllabus, but prioritization matters.
Difficulty Level of Mathematics in JEE Main
Mathematics is usually considered:
Lengthy
Conceptual
Time-consuming
Paper analysis discussions frequently note that maths often feels tougher and more time-taking compared to other subjects.
So practice under time limits is essential.
Daily Study Plan Example
A balanced routine could be:
Morning: Concept learning
Afternoon: Practice problems
Evening: Previous year questions
Night: Formula revision
Consistency matters more than studying long hours occasionally.
