Yeh, I know what you mean about making errors. 🙄 Thankfully, we don't have to hand-write the essay on that form. As to getting around to it, thank the lawd, I've become a little more efficient at this secondaries process (it helps to have one, standard essay question to address). I just Purolator-ed the completed secondary off half an hour ago.
I don't think Georgetown screen applicants, so it's just a matter of time before you get the secondary.
And I believe Georgetown only has one essay, which is "Why this school?" You can go ahead and start writing that (One page limit) if you haven't got the secondary.
