National Merit Finalist (Class of 2019) Questions

My son was notified today that he is a national merit scholar finalist! He is waiting to hear back from most of the schools he applied to. Should he email the schools he has not yet heard from updating his application with this information? Also, he was deferred from his ED school which is listed as his first choice school for the NMSC. Should he change it to “undecided” until he hears back about his outstanding applications, including the deferral?

The difference between NMSF and NMF on a college app is nil. I wouldn’t worry about updating your first choice until you have made a decision.
