Hi Delon,
No, the course software doesn’t give that option. Once you start the test, the timer will count down until the time’s up.
This obviously means that you should start a test when you are reasonably sure that you won’t get interrupted, but we understand that life happens. If you have to abandon a quiz partway through due to circumstances beyond your control, you can either just use your second attempt or send in a reset request (do you know how to do that?)
