if you have a phone next to you or notes or another screen Honorlock will sense that and pause your exam.  I will receive a notice about that.  I’m pointing this out so that you are careful and do not lose points. This exam will utilize Honorlock.  If you encounter issues with Honorlock, I likely cannot help you…so, in Google search for “Honorlock support” and explain your issue to them.  The answers will be visible 1 min after the exam is due, which means there are no opportunities to complete the exam “later”. When you take the exam your exam area must be well lit and you must be visible from the top of your head to your elbows, at least.  Feel free to stand up and take a break, leave the room for one restroom break if needed….relax 🙂 The only resource at your disposal is your huge brain…no notes, phones, web sites, textbook, etc.  You also have access to a basic calculator in Honorlock. Once you begin you will have 40 min to complete the exam.  After 40 minutes, or at 11:59pm, if you have not clicked “submit quiz” Canvas will do so automatically. All you have to do is type”yes” in the space below to indicate you read these helpful reminders.  Good Luck!
