How Has This Been Tested?

The testing for this was conducted by human eye-checks.

npm run dev was the command used to set up the test environment.

All conditions:

• A correct option, resulting in score updation
• A wrong option, resulting in display of correct answer + reason
• Poor, intermediate and excellent performance for all modules of several subjects were checked

AI Usage

• I have not used AI tools for this contribution

• I have used AI tools (ChatGPT, Copilot, Claude, etc.) and I have reviewed, verified, and understood all generated code/content before submitting this PR

If AI tools were used, briefly explain how:

Since creating module-wise quizzes for all the courses is not humanely possible, I fed some agents with the content and requested for questions in the json format. I would recommend setting up some issues to update the test quality and questions.

Additional Notes

• Subjects that were added after the issue was assigned (i.e. DBMS, DOPS, some sections in ML) may not be present, kindly provide me with more time or alternatively allow another issue to fill this up.
• README.md may require updations on how to complete integrating further courses.
• Another observation that was profound - the ML course component had a distinct UI compared to other courses and is not very homogeneous with the rest of the website. Integrating the quiz system into it was hard.
• Would a custom quiz or semester-level quiz be of interest?

The reason it shows up as +7313, -148 for the commits is because the size of quizData.ts has become significantly large to accomodate for the module-quizzes.
