This web-site is where you register the activation/serial number that you have purchased either on-line or from your local College or University bookstore. Registration of your unique Proof-of-Purchase activation/serial number, which was e-mailed to you or found on the printed insert inside the packet you purchased at the bookstore, is required to receive services from (AI)², Inc.

These services include downloads of your required software, on-line adaptive tutorial services, on-line self-assessment services for each topic requested, and on-line chapter-level content-mastery certification testing. The largest obtained certification test score for each chapter is reported to your instructor by (AI)² for use in determining the grade you earn in your course.
