Books

Hi, I'm a freshman in graphic design and web design , and I want to ask if the textbooks "Self, Society, and the Humanities -McGraw Hill," and "Cultural Awareness and Online learning -McGraw Hill," are actually used in the courses, or if they'll just collect dust. Money is quite tight for me at the moment, but I just want to know if it's worth it. If there are any free options, any help would be greatly appreciated.

Ty in advance!
