Robin and exams

Ryan has finished his exams yesterday. At last!

I asked him that day how was his maths paper.

Me: How was the paper today?
Ryan: Very good.
Me: Really? That's good. You know how to do all the questions?
Ryan: No
Me: Then?
Ryan: The paper has my name.
Me: What do you mean?
Ryan: One of the questions has my name.

Apparently, his name was used in one of the problem sums. That's why the paper was good!??

Ian has recovered from his fever but he is no longer Batman. He is now Robin. Why? He says Robin more handsome.
