Inspiration

I wanted to create a simple but practical tool that directly helps teachers save time. Grading quick quizzes or exit tickets can take away valuable planning and teaching time, so I built a program that makes this process instant.

What it does

My program lets teachers enter an answer key and then input each student’s quiz answers. It automatically:

Calculates each student’s score and percentage
Gives a detailed “missed questions” report for every student
Generates a “most missed questions” list, sorted from hardest to easiest, to guide reteaching

How I built it

I coded the project in Java using Replit for development and testing. The program uses:

Loops and conditionals for grading logic
Arrays and lists to store answers and statistics
Sorting to rank questions by difficulty
String handling to validate and clean user input

What I learned

I improved my skills in Java collections, input validation, and program structure. I also learned how to design a project with the end user (teachers) in mind, focusing on clarity and ease of use.

Challenges

One challenge was structuring the program so it’s simple to use for non-technical users while still meeting the hackathon’s requirement to show solid coding fundamentals. Another was ensuring the program could handle different quiz lengths and multiple students smoothly without errors.
