GRE报名后收到名为“Confirmation of computer-based exam”的电子邮件，其中关于“test preparation materials”有说到：“Allow up to four weeks to receive the materials.”和 “You must report to the test center on your test date even if you do not receive the material. ”
请问这俩句分别是什么意思？我还没收到materials,该怎么做，为什么要通知考试中心？
Allow up to four weeks to receive the materials.四周之内应该收到材料。You must report to the test center on your test date even if you do not receive the material.如果没有收到材料，考试当前也必须去考场报道。test center这里就是指考场。没收到就没收到，一样去考。
