Oregon State说没有读MS就申MS 本科就只能MS吗？

有一项专门写了选择appropriate program
还是说这只是说说
可以申PHD

本科毕业可以直接申PhD

Apply to the Appropriate Program
Unless you already have a MS in Statistics, please apply to our MS program. If you are ultimately interested in a PhD, upon successful completion of the MS and approval of the faculty you may be advanced to PhD study.

这么说也没关系吗？目前就看到一个学校说的这么严格
