You must allow the video to fully end and the “Next module” tab to be visible before you can progress to the assessment. If you exit the video before the “next module” tab is visible, you will return to the unfinished part of the course. As with all sections of the course, do not close the window or browser until the “next module” tab is displayed or you will just go back to the beginning of the previous unit within the module. Always use the exit tab to return to the module list when closing down.
