the mockup i created last week would include supplementary information (see below), such as LOR's etc. note that on the development-side, each form field would be stored as a column in a database. therefore, i would still prefer an excel file with the proper columns --- see the link below for which columns to include.
also, although average scores of schools are available, they tend to not reveal the *lowest* and *highest* scores they admit. moreover, the schools do not reveal whether a 3.0 student with a 990 gre score can compete against a 4.0 student with a lower score. realistically, one would assume that's a fair fight. but, some schools are fairly conservative and believe that the high-scoring student slacked off, while the 4.0 student "worked hard" as an undergrad.
(the general picture is there, but: the form currently does NOT work right now. mainly, i have yet to code the server-side processing scripts. do NOT waste your time filling it in just yet.)
