<p>I can't decide whether or not to send supplementary materials.</p>
<p>Do you think if the admissions office welcome ten-sheet supplement or so? And including a two-sheet resume? But would list the activities in detail make my readers bored? How many activities should I limit to? And ... for summer activities, if I have won full scholarship abroad, should I indicate that on my resume?</p>
<p>2 page resume is fine. 10 pages is too much, I think.</p>
<p>As a rule, supplemental material should be interesting and unique - maybe something that sets you apart from most other applicants. Admission counselors will send anything artistic (music, drawing, etc) to a professor in the appropriate Dept. at Williams to review and make final judgment calls.</p>
<p>When I applied last year (I'm a first-year student now), I submitted a 2-pg resume with my application because I had taken a few years off from high school. I then used my application essays to highlight and explain what some of my especially important extra-curriculars were. Generally, if it's too long, an admission counselor will not have enough time to really look over the additional material, as they have so many applications to go through.</p>
<p>Also, be sure not to put down everything you've ever done since eighth grade, but instead include activities that were important to you, where you had a leadership role, anything that had a significant time commitment, anything that you won through athletics (or anything of merit/scholarship -- like your study abroad scholarship), or something that shows another side to who you are as a prospective student.</p>
