I think if it was a standalone question then the answer would be an unequivocal "Yes". So I will present you my situation: while applying to graduate school I had mentioned that two of my papers are under submission at 2 different conferences (I had given the names of the conferences as well). One of them got accepted today and the other one was rejected a few days back.
Now the thing is, I feel that informing them about the acceptance might increase my chances considering this is my first paper and I'm an undergrad currently (is this a myth?). But the issue is, if I inform the committees about the accepted paper alone then I feel guilty about the fact that I'm deliberately concealing information about the rejected paper. And if I don't, I feel I might not be making any use of the fact that the paper got accepted somewhere.
Can someone tell me what could be done?
