I sent some emails to the professor, and told him my information, including GRE/TOEFL scores, university, work experience, etc.
In fact, at the beginning I just hadn't taken GRE. He told me a high GRE score is very important.
About 2 months later, I told him my GRE score, and he just sent an email to the secretary, and I can see the email, too.
I apply for statistics MS.
Some one told that GRE relates to the rank of statistics school, is that true?
