I made the mistake of buying the guides from Chancellor's - another publishing company. Before it was said and done I owed them over $3000, not including the money I still had to pay Excelsior for enrollment and testing and Excelsior will tell you not to buy these guides because they are not at all affiliated with the college. The publishing companies try to make you believe that your testing fees ($215/test x 7) are included in your financing- but look closely, because they are not! Your clinical fees due to Excelsior are not included either! After all is said and done, the guides are helpful- I just passed NC 1 last Tuesday :) however, I would have saved a ton of money had I purchased the books from Excelsior, used my LPN books for reference, and guided my study with the FREE content guides from Excelsior. If you have an extra $3000 to throw away the guides are great, but my intentions were to save money... BTW, if you are one day late on your payment to them, forget about getting anymore guides until you pay IN FULL.
