You dont know how these guys maybe feeling They could be
a) Sore losers
b) Jealous of your perfect score
c) Upset/sad about their own failure
Personally I have been one of the best and one of the worst student in my academic years....and trust me when you fail something last thing you want to do is see the ones who have done really well...Maybe its wrong but we are just humans.
Just put yourself in their shoes what if you had failed the exam how would you react??? AND most importantly why let yourself being affected by others *acknowledgmen*t or lack of it!
