Download latest cbse Class 12 Physics syllabus for the session 2017-18. Class 12 Physics Board exam will consist of 70 marks and 30 marks will be of practical. There will be complete syllabus in your final/annual exam. Each year cbse keep on issuing revised syllabus. Although the topics and textbooks remain same, the contents within vary year by year. Along with Physics syllabus for class 12 cbse has also issued the chapter-wise breakup of questions along with weightage of each chapter. The package also enlists the learning objectives. That’s why it is recommended to download new Class 12 Physics syllabus 2017-18 this year and be on safe side.
We’ve got several queries from students throughout the country regarding their poor performance in the board exams. One noteworthy point was that most of them didn’t bother about the syllabus issued by CBSE, they just practised the sample papers or directly appeared in board exams. It’s very important to avoid such situation and practise at least sample papers issued by cbse and previous year questions. These syllabi are also very helpful for JEE Mains, JEE Advanced, NEET etc.exams. Syllabus acts as prima facie for your CBSE exam. It reduces the topics, tells the weightage of each chapter so that you can invest more time on important topics.
Here we have presented the CBSE syllabus for Physics class 12 in the same format as released by CBSE, without any changes or editing from our side. Students are advised to download the class 12 cbse Physics syllabus for the session 2017-2018 even if you have the previous year syllabus because there might be changes in the syllabus, question pattern and weightage of each chapter.
