经常会有有同学来不及退考，会担心缺考相关的后果。
依据ETS官网的规定：
Absence from a Testing Session
If you are absent from a test session, institutions will not receive any information about your absence or about any previous scores you may have on file.
第二个解释：
If no questions are answered for a specific measure (e.g., Verbal Reasoning), then you will receive a No Score (NS) for that measure.
Abesence from a Test
If you are absent from a test administration, you will forfeit your test fee. Institutions will not receive any information about your absence or about any previous score you may have on file.
下面是网友给 ETS 发电邮后 ETS 给出的解释：
Thank you for contacting the GRE® Program.
Dear Candidate,
Regarding your inquiry:
If you are absent from a test session, institutions will not receive any information about your absence or about any previous scores you may have on file. Score reports will be released only upon your request.
由此可知，缺考损失的只是一次考试费用，所以对gre考试缺考的考生大可不用担心对寄送GRE成绩时产生影响，只有当你有明确的送分请求时，ETS才会寄送你的GRE考试成绩。
