Howdy @jaidenyang112 ,
Thanks for your question. Welcome to the community as well. Hope you did well on your quiz.
You should not receive a 0 if you didn't submit because when the time is up, it auto-saves & auto-submits for you.
If you feel one of your answers might have ended abruptly, it wouldn't hurt to reach out to your instructor and let them know what's up. Hope this helps.
