DESIGN VIEW
The Quiz Maker App is a simple educational mobile application developed using MIT App Inventor that allows users to answer multiple-choice questions and check their knowledge. The app displays one question at a time with several answer options and provides instant feedback based on the user’s selection.
Questions and answers are stored within the app using lists. When a user selects an option and clicks the Next or Submit button, the app checks the answer, updates the score, and moves to the next question. At the end of the quiz, the final score is displayed.
