ya even i dont think there is some prob and why r u bothered if u got more marks chillax dude ...........
but i can believe u coz in their final keys they have given keys for 26-49 in the same color and 50-90 in same colour
no doubt they can mess this too
P.S. i got 1 more mark in verbal getting me a B call coz of that (maybe i dint mark a ques or marked a wrong answer lightly

)
