If you are getting ready for the CBSE Class 12 Maths exam 2026, you don’t need to study everything with the same effort. Some chapters clearly carry more marks. Some are quicker to finish.
So the smart move is simple. Focus on the right chapters first. Then build from there.
This guide breaks down the class 12 maths syllabus, shows you what matters most, and tells you what to actually study inside each chapter. If you follow this properly, your preparation for the CBSE Class 12 Maths exam becomes a lot more manageable.
CBSE Class 12 Maths Exam Syllabus Weightage (2026)
Before opening your class 12 maths book, just look at how marks are divided. This changes how you study.
| Unit | Marks | What it Covers |
| Relations and Functions | 08 | Relations, inverse trigonometry |
| Algebra | 10 | Matrices, determinants |
| Calculus | 35 | Limits & derivatives, Integrals, Differential Equations |
| Vectors & 3D | 14 | Vectors, lines, planes |
| Linear Programming | 05 | Graph-based problems |
| Probability | 08 | Conditional probability |
One thing is clear. Calculus is heavy. Almost half the paper comes from it. So while planning your class 12 CBSE preparation tips, this is where your time should go first.
Important Chapters from Class 12 Maths Syllabus
Now, let us talk about real preparation. Not just chapters, but what actually matters inside each:
Continuity and Differentiability
This is where calculus really begins. If this part is weak, the rest feels confusing. What to do here:
- Understand limits properly
- Learn types of discontinuity
- Practice derivative rules again and again
- Do logarithmic differentiation questions
Do not rush this chapter. Go slow.
Applications of Derivatives
This chapter is scoring and very predictable. You will mostly see:
- Increasing or decreasing functions
- Tangent and normal questions
- Maxima and minima
These questions repeat a lot in the Class 12 Math Paper 2026. So practice matters more than theory here.
Integrals
This one feels long and never-ending, and honestly, it is. But you do not need to panic. The simple way to grasp this topic is to just break it into parts.
| Area | What to Focus On |
| Basic Integration | Standard formulas |
| Methods | Substitution, parts |
| Definite Integrals | Properties |
| Applications | Area under curves |
Do a few questions daily. Not everything in one go.
Differential Equations
This chapter is usually a relief for students. Most questions follow a pattern. Focus on:
- Separation of variables
- Forming equations
- Using initial conditions
If you practice enough, this becomes one of the easiest scoring parts of the CBSE Class 12 Maths solutions.
Matrices and Determinants
These are scoring. But only if you avoid silly mistakes. Key areas:
- Matrix operations
- Determinants expansion
- Inverse of a matrix
- Solving equations
Steps matter here. One wrong step can change the answer.
Vectors and 3D Geometry
This part is a mix of formulas and understanding.
| Topic | Key Focus |
| Vectors | Dot product, cross product |
| 3D Geometry | Line, plane, angles, distance |
Try to draw rough diagrams. Even small sketches help.
Linear Programming
This one is a short chapter consisting of direct questions. Once you practice 5 to 6 questions, you will get the idea. You just need to focus on:
- Form inequalities
- Draw graphs
- Find a feasible region
Probability
Probability is one of the easiest topics to focus on and also one of the most important. You primarily have to give attention to these topics:
- Conditional probability
- Independent events
- Bayes’ theorem
Solve different question types. That builds confidence.

How to Study Smart (Not Just Hard)
A lot of students study for long hours and still feel stuck. The issue is not effort. It is the strategy. Once you get the strategy right, your exam preparation will be pretty straightforward. So what should the correct strategy be? Let us help you with it. Just follow these steps:
Step 1: Stick to the NCERT First
Start simple. Solve all examples, do every exercise, and revisit tough questions. Many questions in the CBSE Class 12 Maths exam come straight from NCERT.
Step 2: Previous Year Papers
This is where you understand the real exam. You should solve at least five papers from the last five years. This helps you notice repeated patterns. This also helps in time management. This way, you will know how long it takes you to solve the paper, and you will be able to time yourself for the final class 12 CBSE exam date.
Step 3: Keep Formulas Handy
One thing about maths is that you cannot mug it up at once. It needs revision and practice daily. In order to revise properly, you must make short formula notes and keep them in a place where you can reach them quickly. Try to revise your notes before sleeping. Even 10 minutes of daily revision makes a difference.
Step 4: Give Mock Tests
Mock tests are very important in order to improve your speed. Try to give at least 3 to 4 maths sample papers before the actual paper. Like this, you will have a practice of sitting for a full three-hour paper with no breaks in between. This will also help you check your mistakes after, so you don’t repeat them on the actual CBSE class 12 maths exam day.
Conclusion
A good strategy and the right guidance can change your Maths preparation completely. At Aakash, students preparing for the CBSE Class 12 Maths exam get focused teaching based on the NCERT. Along with that, there are regular tests, practice questions, and full-length mock papers. Doubt-solving sessions help you stay clear on concepts. Teachers also guide you on how to write answers properly in the exam. With steady practice and the right support, you can improve your performance and feel more confident before the exam.
FAQs
1. Which chapter is most important in Class 12 Maths?
Calculus is the most important section. It includes derivatives, integrals, and differential equations. Together, they carry the highest weight in the paper. If you prepare this section well, a large part of the exam becomes manageable.
2. Is NCERT enough for CBSE Class 12 Maths?
Yes, NCERT is enough if you solve it properly. Most board questions are based on NCERT examples and exercises. But along with that, solving sample papers helps you improve speed and accuracy.
3. What are the easiest chapters to score full marks?
Chapters like matrices, determinants, linear programming, and differential equations are easier compared to others. Questions are mostly direct. With regular practice, these can become your scoring areas.
4. Can I skip any chapter for boards?
It is not a good idea to skip chapters. Even small chapters carry marks. Instead, focus on understanding basic concepts and practising important questions from every chapter.
