When I took the GMAT in March, I had just begun my MBA research, so after further research the 5 schools I sent my score to aren't necessarily the ones I am going to apply to. Schools will know that they weren't included in the "original 5" if I send them my score now. Will that matter?
they wont care. i didnt put a single school down when i took the gmat. many people don't know what schools they will apply to until after the gmat...and the gmat score itself may influence the selection.
