Juvi, Don't be discouraged! If you got to the interview stage that means you were very close and you likely hav ea very good shot at getting into one of the other schools you applied to.
Did you apply to IE? They have a lot of scholarships available; that's one of the big reasons I focused on that school. They even have some 100 percent scholarships if you fit the right criteria (for example, I think there's one for Jordanian women!) Anyway, good luck on your other applications!
Edit: Correction; the Jordanian women scholarship only covers 85 percent, but that's still not bad! There's another scholarship open to all Arab students that would cover everything, even books and living expenses.. there's also a full-ride for American students, but the deadline has passed to apply. Anyway, maybe you aren't applying to IE, in which case this information is useless
