What are the questions to be expected when going for the F1-visa after the stamping is done but couldnt go for FALL?

USA F1, F2 Visas - CPT - OPT

I have got my visa cleared after getting 221g on 4th august 2014.

But due to some reasons I couldnt go for the Fall-Intake and differed my admission to Spring 2015.

But my University has given a new I20 with a different SEVIS ID.

So,I was asked to go for the f1-visa interview again including the OFC part.

What are the questions that I could expect in the interview?
