You can take the advanced right after the basic if you want. I guess you'd be ready when you've got your license and your own bike as they don't provide a bike for you like they do in basic. It mainly goes over some of the things they teach you in basic but with more time and emphasis into what they go over. It's a one day all riding thing, they answer any questions you may have about riding in general also.
so basically once i get my bike and get used to it... go and take the advanced?
btw, is there any place other than on here to look for good deals on bikes?
