<p>A teacher who only sorta knows you but can write the best recommendations in the whole school, or a teacher that knows you well in and out of class, but writes only so-so recommendations?</p>
<p>How do you know anything about the quality of each teacher's recommendations? What is the "best" and what is "so-so"? Personally, I would advise you to choose the teacher who knows you best, because they can speak not only for your academic but for your personal and moral qualities, speaking volumes to an admissions committee and making you stand out from the crowd.</p>
<p>I am with Livedifferent. How do you know? My D starts college next year and we could not tell you what ink her recs were like from different teachers, other than she got into her top school. She never saw them. I think you want someone who knows you to answer the question.</p>
