<p>some of my colleges require one while some require two. for the ones that only require one, is it still possible to submit two and if so is it advised?</p>
<p>It is definitely possible, for the majority of schools at least. I am pretty sure on each website it gives a maximum number of recs allowed, and I would say as long as you stay within that limit, it is all good. :)</p>
<p>Generally, the limit is 4. But if the school only requires one, 2 or 3 should be sufficient. In that case, going over 2 should only happen if the extras are really good or you feel you need them ( say because you had a really bad English grade one year but your teacher still thought you worked really hard and contributed in class, or your family went through a hard time during the semester that your grades dropped, and only a letter from your GC could explain that, etc…)</p>
