I am a currently a senior in high school and I am applying to UNC Chapel Hill by the October 15 deadline. I already have a letter of recommendation from my English and Newspaper teacher and know that I will be receiving one from my counselor. My only problem is that from what I can gather online UNC asks for electronically submitted letters, as do most other colleges, but my English teacher gave me four sealed letters physically. Is this a problem? How should I go about getting any other letters?
