Since due dates in a Range course are hard due dates, you must allow late submissions for all gradable activities so that students are able to move forward in your gated course. Gradable activities include Assignments, Assessments, Discussions, Custom activities, and Journals.
From your Accelerate Education course card, click Editor.
Click the ACTIVITY LIST tab.
From the top menu bar, make sure the view is ALL PERIODS so that you are selecting every gradable activity in your course and not just Q1, Q2, Q3, or Q4 gradable activities. If the view is not correct, click Q1, Q2, Q3, or Q4 and select All periods.
From the Filter by type drop-down list in the center of the page, select Assignment.
PLEASE NOTE: You need to select ONE activity type at a time since activities must be edited within their activity type grouping. DO NOT select Any type to speed up the process; it is not possible to edit all activity types at one time.
Check the box at the top left of the page to select all the assignments in the course.
From the top menu bar, click Bulk edit (pencil icon).
Check the box next to Allow late submissions.
Click the drop-down arrow to the right of Allow late submissions and then select Always.
Check the box next to I understand that these changes are permanent, and I confirm that I want to proceed.
Click UPDATE at the top right of the page.
Repeat the steps above for the following gradable activity types:
