As the KCET exam dates are out, the exam is scheduled for the 23rd (Physics & Chemistry) and 24th (Maths & Biology) of April 2026. With around 75 days remaining, students must focus on the high-weightage and important chapters.
The KCET chapter-wise weightage refers to the percentage or number of questions asked from that particular chapter. In this article, we have discussed chapter-wise weightage for all four subjects in detail.
In 2025, the exam was moderately difficult, with a mix of conceptual, formula-based, and numerical questions.
- Mathematics was the toughest among all, with lengthy calculations in Calculus and Algebra.
- Organic Chemistry dominated the chemistry paper with around 24 questions.
- Physics was a mix of both numerical and conceptual questions, with the highest number of questions from Mechanics.

KCET 2026: Preparation Tips
KCET 2026 requires a disciplined preparation for at least 6 months. However, as only ~ 85 days are left for the exam, you can follow the 3-month plan given below to give your best shot at the KCET 2026 exam:
Timeline Division:
- Month 1: Build strong fundamentals using NCERT textbooks, clear the basic concepts, and make short notes for quick revision.
- Month 2: Focus on advanced problem-solving, mastering important topics, and solving daily sectional MCQs.
- Month 3: Intensive revision, full-length mocks, error analysis, and PYQs.
Daily Routine: Study consistently for 8-9 hours, giving around 2 hours per subject, and the rest of the hours should be used for mock tests, PYQs, and quick revision of what you have studied during the day.
Subject-Specific Tips
Physics
- Practice numerical as ~55% questions are numerical-based.
- Memorise formulas, as direct formula-based questions are common in Gravitation, Thermodynamics, and Current Electricity.
- Graph & diagram-based questions are frequent in Ray Optics, Kinematics, and Waves.
- Solve sectional PYQs for building strong concepts.
Chemistry
- Organic chemistry dominates in Chemistry. Students should focus on reactions, mechanisms, and Conversions.
- In Physical Chemistry, 25-30% are numerical questions. Students should practice calculations for Electrochemistry, Kinetics, etc.
- Inorganic Chemistry has more memory-based questions, which are around 20-25%.
Mathematics
- Focus on the highest weightage areas, such as Calculus (Integration, application, and Derivatives). It accounts for 15-18 questions almost every year.
- Some of the chapters, like Integrals, Matrices& Determinants, Vectors & 3D Geometry, are scoring as they are direct formula-based.
- Students should practice numericals to build accuracy and speed since 60-70% of questions are calculation-based.
Biology
- Must have to complete NCERT thoroughly, as most of the questions are NCERT-based.
- Memorisation is more important than logic in biology as it is a fact-heavy subject with a lot of names to remember.
- Must do high-weightage chapters like Genetics and evolution, Human Physiology, etc.
- Diagrams are extremely important in biology, as diagram-based questions are consistent every year.

KCET 2026 Chapter wise Weighatge FAQs
Ques. Does KEA officially release the chapter-wise weightage for KCET 2026?
Ans. No, the KEA does not release the chapter-wise weightage. It only releases the subject-wise syllabus. The high-weightage topics were estimated by experts and coaching institutes based on the paper analysis of the previous year's papers.
Ques. How is the weightage of questions divided between the 1st and 2nd PUC?
Ans. KEA does not officially bifurcate the weightage between 1st and 2nd PUC. However, based on paper analysis and trends of previous year papers, around 30-40% questions come from 1st PUC and round 60-70% questions come from 2nd PUC. This weightage can vary based on the subject.
Ques. How many questions are expected from the newly added topics in KCET 2026?
Ans. The additional topics based on experimental and practical skills can contribute to around 2-4 questions. This will not affect the weightage distribution significantly.
Ques. How should I use the chapter-wise weightage in my preparation for KCET 2026?
Ans. Students can utilise the chapter-wise weightage in their preparation by focusing more on the high-weightage chapters and skipping the less important chapters. Solving sectional questions and mock tests to increase the accuracy in those topics.
Ques. Which of the physics chapters are scoring and easier?
Ans. Ray & Wave optics, Modern Physics, and basic Kinematics questions are doable if the formulas are revised and practiced.
Ques. Which section of the Chemistry syllabus has mostly numerical questions?
