之前在网上找怎么获取考试折扣的问题，找到的答案都挺模糊，说扫描学生证和在校证明的各种各样的。

然后我昨天发了邮件问, SAS是这么回的

Thank you for your email.  Although you have provided a copy of your student ID, it does not have an expiration date, therefore we need more information.  Please provide additional proof in the form of the following:

•    A currently dated letter from a professor or registrar on university letterhead stating your academic status.

And/or

•    A copy of your current transcript or online course schedule showing your name, the university name and courses you are registered for this semester Spring 2019.

Once additional proof is provided, we will review and issue a voucher if needed.

Thank you.

所以说学生证没用，只有比较官方的在校证明或者本学期课表成绩单才有用。

现在考试都要180，真心贵。。。
