This assignment will use variables, mathematical and logical operators, and conditional blocks

in App Inventor to determine the final grade of a student.

Your program must have

5 text boxes

. The user will enter the name of the student and the

scores of all 4 exams the student took during the semester. Once the name and four exam

scores have been entered, the user will

click a button

to get a message

displayed in a label

letting the user know

the final average and letter grade earned by the student.

Take pride in

your user interface

as it will count for a portion of your grade.

Your program will return the following grades based on the final average of the student:

A: 90 or above

B: 80 to 89.99

C: 70 to 79.99

D: 60 to 69.99

F: 0 to 59.99

Notes: Because you are a genero

us teacher, your app will drop the lowest exam grade when

calculating the final grade average. Because you are dropping the lowest grade, you will not

round up when calculating the final average. When the button is clicked to generate the

average and final

letter grade, the label containing the message should include the student

name

, the final grade average, and the letter grade the student will receive

.

(It looks

like a join block will be used!)

As the creator of the app, you get

to decide the wording of the message

just be sure all

the

information required is in the message.

Finally, make sure

to use variables when creating your app. For reference, when I created a

version of this app, I used 12 variables.

Please submit the .aia file for your project to Canvas by the deadline. To download the .
