I'm doing an application for a master's degree. I have to include a personal statement - this is the only bit where I say why I want to do, why I think I can do it, what I plan to do afterwards etc. All of the rest of the form is factual. Annoyingly there is no guidance as to how long it should be (not even a gap on the form - it's electronic and they tell you to attach it). how long do you think?
