“About a year ago I became homeless and had to withdraw from class leaving me unable to receive financial aid. Being a single mom of two children I couldn’t possibly afford a $200 book, but your book made it possible for me to go back to school without the stress of “how will I afford it.” Thank you! I really hope openstax grows, because you guys are providing a way for me and many others to get a better education so we could better our lives.
- Jenny, community college student
