API for Question Retrieval

• Endpoint: GET /api/test/:id/questions
• Trigger: Invoked when the user clicks Start Test
• Data:
  Returns the complete list of questions associated with the selected test.
  (Screenshots for MCQ and Code questions can be referenced here.)

Handle both coding and MCQ type submissions

Store relevant fields: (refer schema)Add additional fields if required

Evaluate answers server-side:

For MCQ: match against correct option (use the testAns method(), implemented separately)

For coding: run using compiler API and compare output (use the testCode method(),implemented separately)

Store result (pass/fail/partial), marks scored, and time

Once this is done:

Users should be able to submit answers during contests

Submissions will be automatically evaluated and saved

Submission data will be used later to calculate leaderboards
