Here we present to you the latest updated syllabus of class 12 physics subject for the year 2024-25. Every student requires notes which are completely simplified, understable and most importantly self learning because of the vast syllabus. Class 12 physics Ezeenotes is designed and crafted in such a way that every student requirements are fulfilled in best way possible.
Reading or understanding the topics can be very difficult for students but, Ezeenotes every page is crafted with clarity so that every students feels easier to understand the topics. The best part of our notes is the attractiveness in every page.
Complete Overview
Let’s discuss about the syllabus portion of the subject class 12 physics 2024-25, to be specific there ae totally 14 chapters in the complete syllabus. The total period period of learning is prescribed as 160 hours of total lecture required to complete the syllabus.
All the 14 chapters are divided in 9 units totally which are Electrostatics, Current Electricity, Magnetic Effects of Current and Magnetism, Electromagnetic Induction and Alternating Currents, Electromagnetic Waves, Optics, Dual Nature of Radiation and Matter, Atoms and Nuclei and Electronic Devices.
Clear Thought Process
We don’t want students to memorize or by heart the topics without exactly understand the concepts behind the topics, rather every student must focus on conceptual learning to excel in your academics. The best way to study physics is to understand the concepts firstly then learning through the visual representations or the diagramatic approach to understang things quickly.
Exam-Ready Strategy
At the end it’s all about the 30hour exam that decides students fate, so by keeping in mind that its all about the exam class 12 physics ezeenotes includes – ‘all topics covered according to new ncert pattern’, ‘numericals solved’, ‘previous year questions with solutions’, ‘all derivations are handwritten’, and additionally ‘video explanations for all derivations with concepts by author himself’. Making sure you’re fully prepared for the board exams.
