Also, each activity is assumed to finish as-soon-as-possible — based on its assigned start date and its calculated duration.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
