XAMonline is a Print On Demand publishing company

XAM carries relatively low pre-printed inventory of our study guides. We are a Print on Demand (POD) company which means that when a book is ordered it is printed within 12 hours and shipped to the teacher, school, or bookstore. This gives us the versatility to submit changes to our books and have them take effect within 24 hours.


We truly appreciate the feedback that we receive from our customers. XAM Online is a company that listens to its customers. Not only do we listen closely we act quickly on comments and suggestions that are given. Nobody knows more about what our customers want, than our own customers. Please contact us here and let us know if you found an error that you don’t see on these pages and it will be immediatly forwarded to our editing dept.
“I worked about half-way through the XAM book then focused on the practice test. The actual test was very challenging, but I did pass on my first attempt, and I passed by a large margin.”
