CBSE Physics Practical Class 11 -CoolGyan

The Central Board of Secondary Education provides a well-structured syllabus for the CBSE Class 11 Physics practical examination. The Class 11 Physics CBSE practicals consists of various interesting experiments which are also essential for their final marks. So, students must handle their Class 11 Physics practical exams diligently to perform better in the final exam. The Physics Practical CBSE Class 11 is given here to help students prepare for their exam. It carries a total of 30 marks. Two experiments, one from each section carry 8+8 marks, with Practical record (experiment and activities) for 7 marks and Viva on experiments, and activities accounting for 7 marks. Along with the projects and experiments, students must also prepare for the viva questions on the experiment. Students should practice graphs and diagrams as they are essential parts of the exam.
