<p>One rec usually gets written. That rec is usually copied (although obviously if the name of the college appears in the rec then that is changed or if a specific aspect of the college in question is address that is also changed) for each college. I’ve seen some ppl on CC say their teachers personalize every rec though so it depends on your teachers. However, a strong personalized rec is no better than a copied rec if the copied rec is equally strong.</p>
