Before starting an online test students and/or candidates can be given instructions.
Instructions are very helpful in the sense that users have prior information about what waits for them.
With the latest release of the exam software (v. 8.0.17), you can now setup a custom content which is going to be displayed when a step of a task is completed (aka. consumed).
So, just like instructions which is shown before starting a test, you can now prepare a content page which is to be shown after a test is complete.
