Starting with 0 or only a few credits, what is the fastest anyone has finished?

John Bear has mentioned that he knew someone who studied for a few weeks and took four GREs over the weekend to complete a bachelor's from Excelsior. This was, however, way back when Excelsior awarded 30 credits for passing GREs in the 40th percentile, before capstones and when you could schedule a few GREs in such a short time span.

Not only that, even if a college like COSC or something still accepted the subject GREs, and multiple ones at that, ETS won't give anyone the opportunity to take 4 in a weekend anymore. All subjects are tested at the exact same minute, exact same day, so you can't take more than one test in April, October or November. In fact, when I took the psych GRE I asked the proctor if I could use the Monday testing option so that I could have a possible retake of my psych on the Saturday and a first pass at the mathematics subject that Monday. She said you can call and try but basically I had a snowball's chance in hell. If you don't have something like a religious conflict with Saturday the Monday option isn't an option.
