Good luck Padawan. There are plenty of peeps who are in the same boat as yours (including myself, though a bit less than 5 years for me). This site is extremely well-organized and is filled with all different types of people. I recommend you checking out some of the Moderator's post about how to start studying for the GMAT. If you have any question about GMAT, feel free to post and I'm sure you'll hear a response in no time.
