I managed to use abbreviations to list all the schools. I'm still sitting on the application before submitting. We're at a catch 22 really. If we don't list the schools - we directly ignored their directions (they might not like that). If we list the schools then they know where we applied to and that we got in no where which they can assume a number of things about us from this point.... Here's a scenario that comes to mind (it probably isn't anything remotely like this, but whatever):
Several committee members sit in a stuffy little room. The fluorescent lights above flicker and buzz in fixed intervals. In front each member is a stack. In each stack are medical school applications, dozens of them.
An older gentleman pushes his glasses up his nose and speaks, "Alright, what do we have here. Hmm, ew, this is a peculiar looking fellow. Let' see... name is Corvus Brachyrhnchos... Oh. He's a re-applicant, great. This will be easy. Looks like he applied to 22 different schools. He didn't get in anywhere."
"Wow, what a talentless peasant," cries one younger member with a wickedly sinister smile.
"Hmm, indeed, indeed. Looks like we made the right call last time," the gentleman replies.
"Yep, let's put this with the others. **** this guy, " another member declares.
The old gentleman, with purpose, loudly stamps the application with big, bright and red letters that read DO NOT ACCEPT. He turns to his assistant who eagerly stands by, clipboard in hand. "Shred this piece of **** with the others."
