Gus Mattammal, Director
Gus Mattammal, the Director of Advantage Testing of St. Louis, is a born-and-raised St. Louisan (before you ask, he went to SLUH!). Under his leadership, Advantage Testing is already helping students from the St. Louis area achieve their academic goals.
Working in concert with educators, counselors, and learning specialists, we develop individually tailored programs that are designed to complement a student’s schoolwork and achieve a consistent strategy for success. We offer both test preparation and academic tutoring, including the development of custom curricula for students who seek academic enrichment beyond what their schools may offer.
