**Textbook & Access Code: **The textbook,online quizzes, and additional help materials will be made available by logging into

**CASA Campus Services**(

**CCS**) at https://ccs.casa.uh.edu/ . Students pay for access to CCS as part of their fee bill via CTAP. If one opts out of the CTAP, they can purchase an access code for this course at UH Bookstore. In this case, if the code is not entered by the deadline specified on CASA, students will lose access to CASA. No make ups will be given for assignments missed during the no-access period.
