Hello,For most postgraduate programs, the GRE General test scores are required regardless of whether the applicant submits additional GRE Subject test scores. The GRE Subject test requirement varies from university to university. In some cases, a GRE Subject test in Biology will be required.Therefore, you must give the GRE General test regardless of the Subject test criterion. If the GRE subject test in Biology is not required by the postgraduate program that you are interested in, you can still submit GRE Subject test scores in order to gain an edge over other applicants.For more information about the GRE, visit: https://studyabroad.careers360.com/exams/gre
