It is also wise to note when you call the schools, and who you talked to and what you talked about. Also keep copies of all your emails in your sent files. That way you won't send the schools something or ask them something that you already did. That would be embarassing.
Also. File each school's emails into different files on your email account. It makes it so easy to be able to reference something you got from a school.
And lastly, keep your email account from getting full. AND sometimes the emails from the schools end up in the bulk folders. Check those daily so you don't lose something. I remember when the secondary request came from Univ of Ill at Chicago. It was from a weird name, not the school's name and it was in the bulk folder in my yahoo account. I almost deleted it without reading it.
