  3. Standardized test score
    • GRE: ETS Code 4852. To qualify for admission, a student must take the Graduate Record Examination (GRE), and a minimum score of 300 is expected. Students with lower GRE scores should consider applying to USC’s International Academy, which offers pre-master’s programs designed to improve test scores, academic skills, and English-language proficiency, in order to increase the candidate’s chances of gaining admission to our master’s program.
    • MCAT: Alternatively, Medical College Admission Test (MCAT) scores may be provided and will be considered in place of the GRE if they are a minimum of 28. (Admission based on MCAT scores will be on a conditional basis, however, and GRE scores will have to be provided during the course of that student’s first semester.)
