Applicants may submit either GMAT or GRE scores. The selection committee looks for scores that show solid quantitative and analytical skills. There is no set minimum score, however, applicants are expected to be able to display a high degree of competence on all sections of the tests. Applicants are required to release their official online scores for review by the selection committee. Scores must be from tests taken from within the last three years before your application. Scores from tests taken more than three years before your application will not be accepted.
For GMAT the code to give GMAC in order to release your scores to Rikkyo University is: KNH-FJ.
