How to Register for a GRE® Subject Test

The GRE® Subject Tests are offered at paper-delivered test centers worldwide up to three times a year in September, October and April. You can register for a Subject Test online or by mail.

Note: By submitting your registration for a GRE Subject Test, you are agreeing to abide by all procedures and policies for all forms of test delivery (computer-delivered, paper-delivered at test centers and at-home testing) in the GRE® Information Bulletin, on the GRE website or communicated to you at the test administration for which you have registered.

Online Registration

  • You need to create or have an ETS account to register online. Watch a quick video on how to create your ETS account.
  • American Express®, Diners Club International®, Discover®, JCB® , MasterCard®, RuPay™ Global , Union Pay®, or VISA® credit/debit cards are accepted. Payment by e-check (drawn against U.S. bank accounts only), PayPal Information and voucher numbers are also accepted.
  • If you are testing in Nigeria, only Visa, PayPal and voucher numbers are accepted.
  • After entering your credit card account number and selecting "Process Payment," you may be given the option to pay in the currency supported by your card issuer or in USD.
  • ETS processes payments with your security in mind. This may impact your online experience. American Express SafeKey, Discover ProtectBuy, MasterCard SecureCode and Visa Secure/Verified by Visa are 3D Secure (3DS) online fraud prevention measures used by card companies as an added layer of security to protect cardholder account information. During the payment process you may be asked by your card issuing bank to verify cardholder identity by entering an authentication code known only to the cardholder and the bank. Failure to enter the required information or entry of invalid information will result in the sale being rejected. If you don't know your 3D-Secure passcode or password, and you are not being given the option to enroll online in the bank's pop-up screen, then you will need to contact your bank.
  • Online registration is not available for test takers with disabilities or health-related needs. Please see Disability Accommodations.
