<p>I know on Harvard's website it says that they do accept additional recommendations from people outside the classroom. Would it be a bad idea to send in a third teacher recommendation from a teacher who knows me really well?</p>
<p>I wouldn't unless it is a teacher who knows you primarily for an outside non-classroom activity.</p>
<p>if you are sure that it will be extremely positive, i say send it in b/c i read somewhere that harvard weights the recs INDIVIDUALLY.... as opposed to grouping it into a "rec" category for two recs, I mean.. if that makes sense..</p>
