Improvement
Great News! Now you can set an option to resume a test when a student exits a test, either intentionally or unintentionally, before finishing the test and you want the student to continue the same test.
when creating a new test or edit an existing test and go to "Step 2 - Advanced Settings" and select option "Allow user to resume test session?" to "Yes" and save your test.
Please note that this feature is available only for standard scoring and partial-credit scoring algorithms. Adaptive tests cannot be resumed and it requires the test to be completed in one sitting.
When you resume a test, you are resuming the student’s test from the point at which the test was interrupted.
