The cost for books, supplies and tools will vary according to courses taken and the student's major. Some courses are offered with Open Educational Resources (OER) and have no textbook cost. This information is included in the comments for classes during registration and listed as "TXTO". Some courses have an Interactive Digital Access Program (IDAP) fee which is automatically added to a student's MYUH account. The amount of the IDAP Rental charge will depend on the material being used in your course(s). See the UH Bookstore for more details about IDAP.
