Basically the question is just the same as the topic. Is it possible to augment an application after you've already submitted it? I'm still waiting to hear back from almost every M.Sc. school I applied to (which wasn't many to begin with), having been admitted to one. That being said, I was wondering if it was frowned upon to update the schools I'm waiting on about items that would definitely make me a more competitive candidate? Or is it on a case to case basis? Has anyone done it before, and if so, what were the results of doing so?
