you link your account from your ps3 or xbox to the rockstar social club site, then from that point on everything you do gets tracked on it, theres A,B and C lisences C being the lowest, basically its a clipboard with 12 objectives, IE Drive a total of 1000 miles, it shows how far you had driven at that point. once you pass one class you move onto B then C the ferther you go the more daunting the tasks, but along the way you unlock hydrolics and eventually the Audi R8
the social club also has some other things to it, most interactive besides the drivers tests is the photo album you can take in game photos then hit publish (in game) wait about 5 minutes max then your album of pics are on your social club site page and you can save them.
