<p>So I've been emailing the admission office several times over the course of few months about different questions, some of which are simple, some are not...</p>
<p>NOW i am wondering whether I am doing too much. Certainly, I don't want to appear annoying. Also I think I need to call them again tomorrow... Any experience?</p>
<p>Quite a lot. An email every day might be over the top, but they are not gonna mind one or two emails per month. From June to December, communicating with prospective students is their main job!</p>
