As exams approach, all students are most likely busy in preparations, but have you studied for your practical exams? An essential part of the CBSE final examinations, the 30 marks worth practical exam is often overlooked and ignored. Do you know all your theorems, laws of motion and numericals, do you know all the experiements and viva answers in your Physics Class 12 syllabus? Here are some tips!
