I need a little help. I was just informed that I have been invited to an interview at Ohio State Jan, 7th . My problem is that I wanted to schedule my Upenn interview at the same time but the earliest I could get was the 12 of Jan. So I thought I would ask Ohio if I could switch my interview to the 28th and go to UPenn at the same time in order to save traveling money. Would this be wise, or should I just fly out twice?
