You did well - congratulations. I know some very sharp people like that too but they are not common. Most people take a lot longer.
There is a slightly reduced theory coming in, due late 2009. The reference is a page on the CAA website somewhere. This was worked out 1-2 years ago (took several years to get there, I gather) but then it got delayed due to some technicality over the study material provision or something like that.
