well Fahad bhai you are 100 % right but bhai i dont suppose that 90 people will get over 80 %... it means 90/1200 that is approximately one in twelve.... and i dont suppose that one out of twelve can score that much..... just have in mind the percentage of those who pass css............ well what i think and know from one AD in IB........

and also Fahad bhai everybody is not genius like you who can go over 85 %.........
