Subscribing to the Strathena club provides access to:
. all the course videos;
. all the quizzes;
. all the game sessions that allow you to train on advanced concepts covered in the course (life cycles, substitution, BCG matrix, supply/demand ratio, share issuance and buybacks, external growth…);
. the Q&A space for interacting with Xavier Fontanet and Interactive 4D;
. the beta-testing program that allows you to test new game sessions in advance.
Subscribing also grants you a completion certificate from the platform, once the quizzes and all game sessions are completed, subject to a minimum score (email strathena@interactive4d.com to receive it).
