Most Important Chapters for Class 12 Maths 2026
Below is a clear explanation of the most scoring and repeated chapters.
1. Relations and Functions
This is an easy and scoring chapter. Questions come from types of relations, domain, range, and compositions. Every year you will find at least one question from this section.
2. Inverse Trigonometric Functions
Students love this chapter because formulas are simple. One-mark and 2-mark questions come from properties and principal values.
3. Matrices
This is one of the highest-weightage chapters. Questions are usually direct and formula-based. Learning matrix operations makes this chapter super scoring.
4. Determinants
Almost every year, a long question comes from Determinants. Practicing adjoint, minors, and applications helps in scoring full marks.
5. Continuity & Differentiability
This is a big chapter and very important for the exam. Many questions in the paper are asked from limits, continuity, differentiability, and chain rule.
6. Applications of Derivatives (AOD)
AOD is used for real-life problems like increasing/decreasing functions, maxima/minima, and rate of change. Long questions often come here.
7. Integrals
One of the most important units in the entire syllabus. Students must spend more time here. Integration by substitution, partial fractions, and integration by parts must be practiced daily.
8. Applications of Integrals
Easy and scoring. Mostly area-based questions from curves are asked.
9. Differential Equations
This chapter has a predictable pattern. Solving differential equations using standard forms makes this chapter simple.
10. Vector Algebra
Vectors are completely formula-based, so even weak students find these questions easy. Use diagrams to understand direction and magnitude.
11. Three-Dimensional Geometry (3D)
3D Geometry is always an important topic. Questions come from lines, direction ratios, and angles in 3D space.
12. Linear Programming
This chapter is very short and easy. Almost all students get full marks here because questions are direct.
13. Probability
A scoring chapter if concepts are clear. Questions include conditional probability, Bayes theorem, and random variables.
