确认上面这段话是不是会寄准考证的意思？好象ibt没准考证的，难道gre及sub有准考证吗？谢谢！
In about three weeks, you should receive your admission ticket confirming the details of your test registration. Use the Correction Stub to make necessary changes and forward it to arrive at ETS no later than the Friday before your registered test date. If you do not receive your Admission Ticket and Correction Stub at least 10 days before the test date, call 1-609-771-7670 or 1-866-473-4373 (toll free for test takers in the U.S., American Samoa, Puerto Rico, U.S Virgin Islands, and Canada).
