<p>Would colleges mind if you send in ONE extra rec? If not, then should you use the college's rec form (if they dont use the common app) or use the common app rec form regardless?</p>
<p>It depends. Can this person say something about you that no one else can? If it's just another teacher, i'd skip it. If it's someone like a coach, boss, or research mentor, then go for it. They would probably just have to write a separate letter since most questions on the teacher rec won't really apply to them.</p>
