Quote from Bozz
Has anyone heard of The College Network?
We have, but not everyone thinks it's a great idea to use them. You're going to be paying substantial fees to Excelsior anyway, so signing a contract with a publishing company for study guides will only add to the cost.
In most cases, you can buy EC's recommended textbooks and use them for several of the classes. Some people even check them out from the library and return them. There should be a ton of threads regarding Excelsior as well as The College Network on this site. Use the search function and you'll come up with a lot of info here.
