CBSE Class 11 Physics Practicals would be conducted for 30 marks that would be added to a student’s final score in the CBSE Class 11 Physics Annual Exam 2022-2023. Therefore, students should take the practical part seriously so that they can boost their overall scores. They must know the practical syllabus and evaluation scheme and should learn the step-wise procedure for all the experiments mentioned in the syllabus below. Students can check and download the CBSE Class 11 Physics Syllabus 2022-2023 in PDF.
