MUS 116 w/ Michael Galasso @Fullerton CC

I know this is at Fullerton College, but has anyone taken him before for a summer class? He is asking us to purchase a book that is $101 when the class is only a month and a week long... The book is called Music 116 Package w/connect. I found a PDF file of the book but not sure if it will be the same. It’s the same author and edition and everything but ya’ll think I should just buy the book in case? What is throwing me off is the “connect” part of the title lol.
