QUOTE:
To add, correct or change GRE score recipients on your registration form, make the desired changes on the correction stub attched to your admission ticket. Mail the stub so that it will reach ETS no later than the Friday before the test date for which you registered. You may also e-mail your corrections to gre-info@ets.org. Any requests to add, delete or change score recipients received after the Friday before the test date must be accompanied by $15 per institution.
