Account Registration and Subscription


To access the case teaching notes and answer keys for the case studies on our site, you must have a registered account and paid subscription. (Access to the case studies themselves do not require a login.)

Only teachers are eligible for an account. Moreover, each individual teacher must have his or her own registered paid account. Account login information and/or printed material cannot be shared with other faculty; accounts will be suspended if there is a violation of sharing.

Access to answer keys and teaching notes requires that you register with us, and if approved, pay an annual subscription fee of $25.00 (online credit card only).

For schools with more than two teachers requiring an account, please email the NCCSTS Administrator at nccsts@buffalo.edu.

  • Reproduction, reposting, or sharing of answer keys and teaching notes is strictly forbidden.

  • We reserve the right to confirm the identity of anyone attempting to register for an account as well as to log and review activities on our site and other sites using/misusing our materials.
  • If we reasonably believe that activities which compromise the confidentiality of our answer keys and teaching notes have occurred, we reserve the right to cancel your subscription without refund or notice and to block access to all users from that IP address.

I hereby acknowledge and agree to the rules and restrictions above. (Please Check)
