Karnataka 2nd PUC PCMB Syllabus 2026-27: Subject-Wise Units, Marks & Exam Pattern

2nd PUC PCMB is the decisive board year for students targeting medicine through NEET or engineering through KCET/JEE. This page gives you a subject-wise overview of the 2026-27 KSEAB 2nd PUC syllabus, unit lists, and marking scheme, with links to the full syllabus for each subject. The science subjects stay largely NCERT-aligned with Karnataka state modifications, and unlike 1st PUC, these are the marks that actually feed your admissions.

What Is PCMB & Why 2nd PUC Marks Matter

Physics, Chemistry, Mathematics, and Biology (PCMB) is the combination that keeps both medical and engineering routes genuinely open, since it carries Biology alongside the full PCM core. This is what sets it apart from PCMC, which swaps Biology for Computer Science and suits students already committed to engineering or CS/IT. Here’s what makes 2nd PUC different from 1st PUC: these marks count directly. Your Biology score (as part of PCB) affects your NEET eligibility, and your Physics, Chemistry, and Mathematics marks affect your KCET rank, calculated as a 50:50 weightage between your Class 12 PCM marks and your KCET score. In other words, this is the year where your board preparation and your entrance preparation genuinely overlap, and both matter equally.

Karnataka 2nd PUC Exam Pattern & Marking Scheme (PCMB)

PCMB uses a mixed marking scheme depending on the subject.

Physics, Chemistry, and Biology follow the 70 theory + 30 practical split, while Mathematics is the exception at 80 theory + 20 internal assessment, with no practical component. Each exam runs 3 hours. Under current KSEAB norms, the subject-wise passing minimum is at 30% of the theory component (21/70 for practical subjects, 24/80 for Mathematics), with a 33% overall aggregate required. Repeaters and private candidates answer a full 100-mark paper without the practical or internal split. And to repeat the point that matters most here: these 2nd PUC marks are what actually feed NEET (via your Biology/PCB performance) and KCET (via your PCM marks in the 50:50 rank formula), unlike 1st PUC, which is purely a foundation year. Always verify current-cycle passing percentages against the official KSEAB blueprint, since these have been revised recently.

Physics Syllabus Overview (Class 12)

2nd PUC Physics covers 15 chapters across major units including Electric Charges and Fields, Electrostatic Potential and Capacitance, Current Electricity, Moving Charges and Magnetism, Magnetism and Matter, Electromagnetic Induction, Alternating Current, Electromagnetic Waves, Ray Optics and Optical Instruments, Wave Optics, Dual Nature of Radiation and Matter, Atoms, Nuclei, Semiconductor Electronics, and Communication Systems. It follows the 70+30 (theory+practical) scheme and stays NCERT-aligned. See the full Karnataka 2nd PUC Physics Syllabus for the complete chapter-wise breakdown.

Chemistry Syllabus Overview (Class 12)

2nd PUC Chemistry spans 16 chapters, including Solid State, Solutions, Electrochemistry, Chemical Kinetics, Surface Chemistry, General Principles and Processes of Isolation of Elements, p-Block Elements, d- and f-Block Elements, Coordination Compounds, Haloalkanes and Haloarenes, Alcohols/Phenols/Ethers, Aldehydes/Ketones/Carboxylic Acids, Organic Compounds Containing Nitrogen, Biomolecules, Polymers, and Chemistry in Everyday Life. It follows the 70+30 scheme and aligns with NCERT. See the full Karnataka 2nd PUC Chemistry Syllabus for the complete unit breakdown.

Mathematics Syllabus Overview (Class 12)

2nd PUC Mathematics covers Relations and Functions, Inverse Trigonometric Functions, Matrices, Determinants, Continuity and Differentiability, Applications of Derivatives, Integrals and their Applications, Differential Equations, Vectors, Three-Dimensional Geometry, Linear Programming, and Probability, across 13 chapters. Mathematics uses the 80+20 internal assessment scheme, with no practical component, unlike the other three PCMB subjects. See the full Karnataka 2nd PUC Maths Syllabus for the complete breakdown.

Biology Syllabus Overview (Class 12)

Biology both defines PCMB and is the most NEET-critical subject in the combination. The 2nd PUC Biology syllabus is grouped into five broad units: Reproduction, Genetics and Evolution, Biology in Human Welfare, Biotechnology, and Ecology. These units carry direct, heavy weightage in NEET Biology, so treat this syllabus with real seriousness rather than as just another board subject. It follows the 70+30 theory-and-practical scheme. See the full Karnataka 2nd PUC Biology Syllabus for the complete chapter-wise breakdown.

How to Use This Syllabus + Prep Tips (Board + Entrance)

Given the stakes this year, use the blueprint to prioritise high-weightage units first, since your time here does double duty for boards and entrance exams. Lean into the NCERT alignment deliberately, since strong NCERT command directly strengthens both NEET and KCET preparation, not just your board exam. Keep your practical records well organised through the year for the 30-mark practical components in Physics, Chemistry, and Biology. And plan your board and entrance prep together rather than as two separate tracks, since your Biology performance feeds NEET directly, and your PCM marks feed exactly half of your KCET rank. If you’d like structured subject notes or coaching that ties your board and entrance preparation together, Giraffe Learning’s NEET and KCET programmes in Bangalore are built around exactly this overlap.

FAQs

Q1. What subjects are in 2nd PUC PCMB?

Physics, Chemistry, Mathematics, and Biology, plus the two languages — keeping both medical and engineering routes open.

Q2. Do 2nd PUC PCMB marks matter for NEET and KCET?

Yes. Biology/PCB feeds NEET eligibility, and PCM board marks feed the KCET rank, which uses a 50:50 weightage of Class 12 PCM and KCET marks.

Q3. What is the marking scheme for 2nd PUC PCMB subjects?

Physics, Chemistry and Biology follow 70 theory + 30 practical; Mathematics follows 80 theory + 20 internal assessment (no practical).

Q4. Is the 2nd PUC PCMB syllabus based on NCERT?

Largely yes, the science subjects follow the NCERT framework with Karnataka state modifications, which also helps with NEET and JEE preparation.

Q5. Can PCMB students take both NEET and KCET?

Yes, that is PCMB’s main advantage. Biology enables NEET while the PCM core enables KCET/JEE, so students can pursue medicine or engineering.

Q6. Where can I download the official 2nd PUC PCMB syllabus?

From the Department of Pre-University Education / KSEAB website. Always cross-check unit lists and the blueprint against the latest official PDF.
