Just how quick was it?
Went like this:
Credit approval
Paperwork automatically sent to my uni for signature and return (this is the step that broke down for me- IEFC had the wrong fax number for my university on file so the stuff they sent never got there and I had to get them to resend to the right fax number. But if this goes through first time like it's supposed to, then this happens within a day or so of your credit approval.)
University signs paperwork and returns it to IEFC (they can do this via fax, so as long as they're diligent about it, can be done within a day.)
Final approval of loan - 48 hours after all paperwork received.
So theoretically, you could have all this done inside of a week if everything works smoothly and goes according to plan, but of course things happen so you have to keep on top of each step. Once I realised that the loan paperwork had never reached my uni, I spent some time on the phone with IEFC sorting it out and then spent some more time on the phone making sure my uni did it in a timely fashion, and had my loan approval about a week later.
