<p>I submitted all my applications already, however I just got selected for the National Biology Olympiad( one of 6 people from my state).
(I am applying for Biological sciences)</p>
<p>Is it worth adding this into my admissions file? If it is, How do I do it?
(Email, Post?)</p>
<p>I second the idea of calling admissions. You do not even have to give your name. Ask them whether you should let them know, and how. You can always give something to your GC to include in the envelope with the mid-year report (such as a letter or award that can be copied).</p>
