, we need to analyze their answer to calculate their score.
To do so, we simply need to check whether every single question is selected or not.
It is up to you to decide what will happen. You can have 1 global score, and some answer can add 0 point, 1 point, 2 points, or even decrease the score. You can also have different score (for example ¡°which element are you¡± would be testing your score according to the different elements).

Analyze of the answers Everything will be done inside the function ¡°Button_Clicked¡±.
First of all, create your variable ¡°score¡±. Remember that you can have more than 1 variable ¡°score¡± depending on your quiz.

Analyze of the answers
You can access to the property ¡°IsChecked¡± using each x:Name.
You will create an ¡°if conditional¡± for each answer. If the answer is checked (IsChecked == True), then the user chose that answer.

Analyze of the answers
Then you simply need to add or remove points according to the user answer. For example, in this example, if the user choose the answer 1 for question 1, he will get 1 point. If the user choose the answer 2 for question 1, he will lose 3 points.
You need to do this for every question and every answer.

Analyze of the answers
After calculating the score, you need to show the result accordingly. Simply compare the score with an ¡°if conditional¡±.
Note: If you have different ¡°score¡± variables, you need to compare them to find the highest one.
