How to delete a quiz question i submitted?

Answer 1

Once it's submitted, you CAN'T delete it.
What's done is done

Answer 2

Once a quiz has been submitted, there's no turning back....

Answer 3

If it's wrong, it probably won't be approved, so you've got nothing to worry about

Answer 4

oh no!
I have a feeling the answer is wrong and i made a mistake in the question anyway. Hopefully, people will downvote it. If you ever happen to see a wrong Python question about foo, bars, spam, eggs by me, downvote it immediately. Anyway thank you for the info.
I hope a feature to delete or at least edit submitted quiz questions is introduced in the future.
