If you assume that the interviewer is actively trying to catch you out then yeah what Zelig says is pertinent. But interviewers *want* to hire you, otherwise you wouldn't have been called for interview, so they will give you the benefit of the doubt.
The point isn't that your degree is, in fact, more rigorous that someone else's. The point is that you put extra effort into it, instead of just taking the easy route. No interviewer would question that, because that's exactly what he *wants* to hear. He *wants* you to be a hardworking guy, because your CV is good and he wants to hire you.
