I see your question has been answered. In addition, I'd like to add that there are many levels of purgatory, as there are in hell and also heaven. We choose our destination of our own free will; ie., we are not "sent" there. Because when we die we know all our own sins and although they are "forgiven" already, we must be purified. If they weren't forgiven, we would never have any hope of attaining the purification of those sharing heaven with Our Lord and Almighty Father.
I don't think there are multiple levels of hell, either your soul is damned or it isn't.
