Thanks Farah. Score in viva is "fairly" low. Means it is not unfair. I could have done a lot better, but, somehow, it was not my day.
And yes I opted for Urdu because of my interest in Urdu as well as international literature. I had already been through the recommended books. So did not find need (in fact time) for any special preparation. Papers were also very easy. Essay length exactly tou yaad nahi ... perhaps around 10 pages each.
