With the exception of lab sciences, eCore courses utilize open educational resources and do not require you to purchase a textbook. Information on accessing these free resources is available within the courses.
Most lab science courses require a purchased lab kit. Information on how to order these kits can be found on the eCore website. Campus bookstores typically do not carry lab kits, but many are willing to order them for you. You may be able to use financial aid money to help purchase your lab kit. Please consult your home institution's Financial Aid office or Campus bookstore for possible options.
