Please check with your school or instructor for their preferred method of acquiring your activation code. Some schools sell the codes for our TestOut products at their bookstore, while other schools provide to students a Promo code, which can be entered here , enabling students to purchase the appropriate TestOut training subscription and receive a corresponding activation code. Other schools simply provide their students with activation codes or activate student accounts without the student ever seeing the code. For this reason, it is important that you contact your instructor or school for guidance.
In K12, students do not receive Activation Codes. Students receive their licenses from their instructors and admins at their school. K12 instructors or admins can go here to learn how to activate licenses for K12 students: https://support.testout.com/hc/en-us/articles/360037366594-Activate-or-View-Licenses
