关于西北EE的deadline

There are three deadlines for MS applicants:

October 20, 2011 (for Winter 2012)
January 19, 2012 (for Spring 2012)
July 1, 2012 (for Fall 2012).
Applicants for Fall 2012 should expect to be notified within 4-6 weeks after their application package has been completed.

这个算rolling basis吗？？

算啊，这不很明显的说了么材料齐了4到6周后就处理。。。
