I did the reverse...i said A cuz HbR has more mass and it diffuses less...wont i get marks for the idea cuz i just miscalculated the masses

Guys how can person calculate his/her grade using the grade thresholds?

Ok for example in may june 2014 the grade threshold for an A* was 139/200. However the total marks for chemistry are 180 as p1=40,p3=80,p6=60

so make an equation ,

n/180=139/200
n=(139/200) x 180
n=126

So the marks required for an A* will be 126/180 . (Not sure about this method)
