QSM Save and Resume Addon Overview:

Save and Resume plugin enables the ability to save a quiz or load a previously saved quiz session.

AutoSave

It automatically saves every quiz in a separate temporary table whenever a user starts taking the quiz.

Auto Resume

It auto-detects if a logged-in or non-logged-in user started a quiz but left in-between, in which case it tries to auto-resume the quiz where the user left off.

Session ID

Users can manually trigger “Save Quiz” and obtain a session-id which can later be shared with anyone to resume the quiz at that point in time.
