关于恢复GRE成绩取消的问题
我在最近6G考场上一时冲动,取消了成绩.感觉其实并不是那么差,现在想恢复.
于是和ETS发送邮件,得到的回复如下：
Only canceled scores from a complete test (Analytical /Writing,Verbal,and Quantitative sections) can be reinstated if your request is received at ETS within 60 days after the paper-based test date.Mail or fax a written request to GRE.See the mailing address and fax number below.Your request must include your name,date of birth,daytime phone number,test date and registration number,payment of $30,and up to four free score recipients.Include the appropriate department codes.If you do not select score recipients at this time,you must pay $15 per recipient to have scores sent at a later date.
他说可以再60工作日内进行恢复,让我给他发邮件或者传真手写申请书,请问其中那个payment of 30$怎么处理?是交给ETS吗?怎么交呢?
