god.. i'm screwed..

screwed up my maths test.. the question asked for Var(1/x) and i went to find Var(x).. and what? the question stated that X and Y are independent of each other.. and i put Var(4X-Y) = Var(X1)+Var(X2)+Var(X3)+Var(X4)+Var(Y).. gone.. i'll be so glad if i can get 70%.. and some people didn't believe me that i just screwed it up.. gone..

and the econs test.. surprise test.. huh.. let's just say that i'm super screwed in all my subs now..
