<p>I was looking around on the Columbia website today, and I read for the first time that for Engineering applicants, one of the teacher recs must be from a math teacher. I assigned my recs to my physics and history teachers months ago, and now I'm not sure what to do. Should I ask my math teacher ASAP to send in a third rec, or just risk not following instructions?</p>
