i have never heard of a school throwing away a secondary because they did not ahve the primary yet. i would think that if their secondary is online and you can get to it without a password then they would expect to receive some before they had the primaries in hand escpecially since the verification process can sometimes take a while. i would send them in but it does not do you a lot of good since they will not evaluate you until they have your primary in hand.
best wishes in teh application cycle 🙂
