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

These services include downloads of your required software, online adaptive tutorial services, online self-assessment services for each topic requested, and online 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.
