Test Instructions:

1. A third attempt is not allowed. Do your best to complete this test as accurately as possible.
2. Note that the maximum attainable score for this retake test is 70% (210/300).
3. If you passed the first (Theater) test, successfully completing this test will earn 10 extra credit points.
4. Scroll to the bottom of this assignment to download a starting point for the test.
5. This test is "open book", meaning you can use any resources other than classmates as an aid to completing the test.
6. This test is based off of the work completed as part of the assignments from Learning Plans 1 through 3.
7. To increase your chances of successfully completing the test, complete each of the sections of the test before moving on to the next, as subsequent steps build upon the work completed in earlier steps.
8. Use the debugger to confirm that your results are as expected.

Implement the changes specified in the following UML class diagram.

1. When creating classes be sure to:
   1. Ensure the class in the root namespace. This can be done in one of two ways. Either by adding the class in the project, i.e. scenario, or by adding the class to the business classes folder and removing the ".Business_Classes" designation from the namespace.
2. Open the main window (MainWindow.xaml) in designer mode (right-click and click "View Designer" or press Shift-F7 to go to designer mode).

Instantiate the objects and set their field values as specified in the following UML object diagram.

Button details:

1. Write code in the "3.1 Find Luke's GPA" button to find the grade-point average of Luke and store it in a local variable.
2. Write code in the "3.1 Find Merrill's popularity" button to find the popularity of Merrill and store it in a local variable.
