It's easy to spot homework questions by Indian students: they are using Rs. as currency. This is no more of a problem than homework questions in general, of course; and thinking at the number of people living in India, it is no strange that many come here. Still, I have the impression that there are more Indians than the usual share in other similar sites. Does anybody know why this is the case?
(As I stated in the subject, it's just a curiosity - for example, I don't remember homework questions using euro...)
