Yes. Any educational level 9th and higher is fine, including adults, provided you complete the remaining portion of the Great Books Program (a minimum of one year), and take or have taken courses substantially equivalent to the required GHP courses,that are high school level or higher. However The Great Courses Plus™ may not be transferred in as merely watching the lectures does not provide any means of testing and assessing educational outcomes – those need to be taken within/while enrolled in the Greats Honors Program for that reason.
