Hello! You have to take the test all in one go otherwise it will close on you if you choose to leave and come back to it. The instructions say, \”This exam is timed. So DO NOT start the exam until you are ready.\” And it also says this right before starting the exam, \”This assessment is limited to 3 hours, 30 minutes. A timer box will display at the top of your browser window showing your remaining time. Be sure to submit the assignment for grading before this timer runs out.\” I\’m sorry for any confusion and if you had difficulties with this.
