申请Stanford材料系的同学，成绩是不是一定要在学信网认证啊？

昨天收到小米群发的邮件，说graduate admissions department 如果收到我们的final transcript 会给我们发一封welcome email。 但是我没有收到啊！联系了小蜜，说她已经把我申请的时候寄给她的成绩单send到graduate admissions了，她也不清楚什么情况。仔细看了看材料系官网（https://mse.stanford.edu/admissions/admissions-faq），上面说“ If you are offered admission and accept the offer, then your final transcript and your graduate and degree certificates must be submitted to Stanford via the CHESICC method as a condition of your admission. ”。是不是因为我没有在学信网认证啊？
