If you want to make changes to a test/quiz school wide, you need to contact StudyForge and request admin permissions in order to do this.
Reach out to us through email: support@studyforge.net or fill in this form. You must be an Administrator at your school or have permission from your Administrator.
Once we've set you up with permissions, follow the instructions from the knowledge base article - How do I give a student more time or another attempt on a test?
As the song says "I've got the power"🎵 ...and you do, to edit activity settings!
