I went to the info session. The lady who works in the admission, Jenny Barajas, said that the only advantage you have by sending your application early is that they will have time let you know if your course planned will not fulfill the prereq. That's it. There is not advantage turning it now or by Nov 1. I think Nov 1 is not postmarked deadline. Western MUST have your application by Nov 1.
Interview will be done in December and January.
