Karnataka 1st PUC Physics Syllabus 2025–26 | Complete Guide
1st PUC Physics is the foundation year for students aiming at 2nd PUC boards, KCET, JEE, and NEET. The Karnataka 1st PUC Physics syllabus 2025–26 focuses on mechanics, thermodynamics, oscillations, and waves topics that directly lead into electricity, optics, and modern physics in 2nd PUC.
The subject carries 70 marks for theory and 30 marks for practicals, with a rationalised syllabus and clearly defined portions. At Giraffe Learning, 1st PUC Physics is taught with strong concept clarity, numerical practice, and diagram skills so students build confidence early.
Why 1st PUC Physics Matters for Boards & Competitive Exams
Karnataka 1st PUC Physics builds the base for almost every chapter in 2nd PUC Physics. Nearly 40% of the KCET Physics syllabus comes directly from 1st PUC topics, especially mechanics and thermodynamics.
The syllabus includes 15 chapters, starting from Physical World and ending with Waves. Students who understand motion, forces, energy, and graphs clearly find 2nd PUC topics like electrostatics and optics far easier.
With consistent preparation, students can confidently aim for 55+ out of 70 in theory, while practical marks strengthen overall board performance.
