The complimentary manuals we send with the enrollment in TX Core Courses are not required for course completion.
We send manuals with our Texas courses as a complementary resource to be used after the online course access expires. We don't recommend waiting for this to arrive to begin making progress in your course. Everything required for course completion is included online and the book is not necessary for the course.
We also recommend expecting arrival of the manual to take several weeks because there is a point in the process that we do not directly influence and often it will take several weeks to process everything.
