That's the most discouraging requirement for me. I've completed the first 18 months of
two undergraduate programmes (without actually graduating),
and half a year of an MSc, before finally admitting that I simply didn't care enough about academia. I have
no idea how'd I ever manage to demonstrate what I've done. I might have a sort of exam booklet somewhere back at my parents', god knows where. I cannot be the only drop-out who's not particularly plussed about storing mementos of his academic failure.
Either require a full degree or drop the requirement. This middle-of-the-road thing is just silly red tape.
