Hey

I am answering this assuming that you are talking about honours percentage. There are 8 papers of 100 marks each in your total course of three years. Two papers in first year, two papers in second year and four papers in third year. After third year your total score's percentage is going to be your final percentage (i.e. suppose you got 100 in first year 100 in second year and 200 in third year. Then your percentage would be 400÷800×100=50%).
