Once you have completed all questions in an Evaluation, you will reach the last Progress Report screen that will show that all Categories have been completed. The button below the last category will now say "View Results!".
When you click the "View Results!" button, you will see the results of the Evaluation in the Quality of Life report (see article Quality of Life report). The Quality of Life report shows an estimate of Quality of Life by category for the Senior and a list of recommended actions.
If you haven't answered all questions, you won't be able to complete the evaluation. Your answers won't be lost but yon't be able to see the results of your evaluation. See this article to understand what happens when you leave questions unanswered (What happens if I don't answer one question?).
