Could you give me an idea on the following two questions?

Because of , the examination process is taking much time than i thought, i'd like to know about the options of applying without scores for the universities before the deadline.

1.do all universities have a common procedure that taking application and Gre and Toefl score seperately before they process the applicaiton?
2.if i had applied to a university without my Gre and Toefl scores, what'd be the window i got to submit those ?
