Hi am Topu i would like to get details on viva questions and answers for bsc physics pdf. My friend Sarkar said viva questions and answers for bsc physics pdf will be available here and now i am living at Dhaka and i last studied in the Govt.Science college and now am doing B.Sc I need help on B.Sc viva question on physics
