I have taken some time to read a similar post at http://forums.awn.com/archive/index.php/t-1150.html
I am now in a similar situation, trying to get accepted to the University of Southern California's summer film program. My case is somewhat different to the above forum thread, as I am limited to roughly 250 words (it says 250-500 words on their site, but on this year's application form, it says roughly 250 words).
Does anyone have any suggestions on what to include? 250 words is not a lot to work with. For reference, this post alone is now up to 98 words..
