Mathematically, the beginning, more or less. I had the advantage of having dropped out of my undergrad, so I went back (after 13 years), changed my major to math (from CS), finished in two years and applied to graduate school. If I hadn't been able to resume my undergrad, I'm not sure what I would have done. Masters? Part-time classes until I'd bulked up my background and impressed a few professors to write me recommendations? I don't think I would have done very well applying straight to PhD programs.
