I believe there IS a process for upgrading, and it is a day of test diving. Whether you pay for it or not is at the discretion of your instructor. Unlike the conversion of a provisional to a pass, which must be completed within six months, you can do the tech upgrade any time.
I highly, highly recommend doing Fundies in a single tank (at least for people who aren't wunderkinder like the guy in the original post) for a rec pass, and taking your time to move into doubles and practice before doing the tech checkout. You will build GOOD habits from the beginning -- and there is an awful lot of good diving out there that doesn't require doubles. One of the best instructors I've ever had said, "Do all the dives you can do with the certification you have, and when you're totally bored, get more training." I think people rush to get into technical training and miss a lot of fun diving along the way.
On the other hand, there are caves . . .
