There are many websites and resources which provide open access textbooks to students. Often these are free, but sometimes require registration.
HOWEVER: Ask your professor before using these textbooks, as they may provide the correct content used in the course.
Although many of these textbooks may not be used in class, they can be useful for free extra practice.
