Early Decision I or II for Boston University

Hello!

I hope to attend Boston University and was hoping to apply Early Decision, but I was not sure about the differences between Early Decision I and II besides the notification date.

I am struggling with my application and feel like I may not make it in time for Early Decision I. Would it hurt me to apply for Early Decision II?

Thank you in advance!
