Additional letters of recommendation

<p>I have 4 letters that I really think provide insight to my character.</p>

<p>2 of them are online on the CommonApp, the 3rd is my IB coordinator’s which was sent via mail, and my 4th is one of my French teacher who wrote exclusively of my interest and passion for French, which is what I want to major in.</p>

<p>Does BC allow more than 3 letters?</p>
