我刚刚去collegeboard上看,在admission ticket上test center是不可以update的。现在我唯一的建议就是call Customer Service at (609) 771-7600 (TTY: 609 882-4118)。因为如果一个人想改test date时上面是这么说的:When you call, be ready to tell the customer service representative your registration number and test date, your social security number, and the credit card number and expiration date. If you do not want to change your test date and would like to request a refund for any additional score reports, Question-and-Answer Service, and Student Answer Service, call Customer Service at (609) 771-7600.
