With effect from 2026 Intake, standardized test scores such as the GRE are optional for PhD (IBM) and (QBM) applications.
You may still choose to submit your GRE scores, and it is encouraged to do so if you believe it will enhance your application. Evidence of strong quantitative, verbal, and analytical skills through GRE scores, as well as indicators of research skills and experience will significantly strengthen your application.
If you choose to enter self-reported test scores, official test scores will become a required component of your application and the official GRE test results must be received by Duke-NUS before the application deadline i.e. 15 Jan. Submitted scores should not be more than 4 years old at the time of admission. Please have your scores released directly to Duke-NUS with the Designated Institution (DI) code of 4915.
Information on the GRE can be found on the ETS website.
For applicants applying to the CTS PhD programme, with the exception of applicants with SMC recognized medical degrees, all other candidates are required to submit Graduate Record Examination (GRE) General Test or MCAT results
