Early Decision 2

I recently learned that some colleges, especially LACs, have early decision 2. Then, are you allowed to apply to both Early Decision 2 to one college and regular decisions to other colleges? or are you limited to applying to only one college?

You can apply ED2 to one school and apply RD/Rolling/EA to other schools as well. However, if you are accepted to your ED2 school you must withdraw your application from your RD schools and attend the ED2 school. It is the same process as if you were to apply ED1.
