Received/Application Complete means that they haven't started looking at your apps yet. Probably reviewing earlier batch of applicants and they are letting you know that they got everything with them so you won't call them. But AADSAS status isn't that reliable, one of mine said, Received/Under review when they haven't even received my secondaries. Now that I was invited for an interview at that school, it still says "Received/ Underreview"
