Is it possible to edit the submitted quiz?

Answer 1

Yes, its possible.
I did a typo in Quiz but it got approved, then I emailed sololearn for correction in it with screenshot of quiz & they corrected it.

If your quiz is not approved, then no need to worry about it, just make a new quiz with correction & submit. (wrong quiz will get declined, if get approved then you can send email for the correction)

Answer 2

You can report a wrong quiz

Answer 3

of course you can edit a quiz after submission if and only if it Is still pending or rejected but when accepted it can't be editted,but as const InvBoy = me; said you can also report a wrong quiz for the progress of the coding community
