<p>Is there a way for us to know that MIT has received supplemental materials (recommendations, etc.) and placed them in our file? Would I be bothering them by calling/emailing the admissions office just to make sure?</p>
<p>yah, do that. thats what i did to make sure MIT got my research paper and another letter of rec (calling them).</p>
<p>I emailed them to make sure they had my supplemental materials, and they responded back quickly saying that they have them.</p>
