Many textbooks have codes to access materials digitally.
Publishers bundle their access codes with new textbooks. Codes are usually not available for used books or rented books, they are typically one-time use. ACHS does not have a way to get codes for students since that is directly provided by the textbook publisher.
However, unless explicitly stated, ACHS does not rely on the extra digital materials bundled with textbooks. We always take care to ensure students have everything they need at the lowest cost possible.
Please refer to your course syllabus and/or instructor for more information.
