Result Doctor

You are reading a University of Delhi (DU) "Statement of Marks / Grades" (marksheet). Convert it into JSON exactly as described below. Accuracy matters more than speed — re-read every row before answering.

PRIVACY: Do NOT include the student's name, roll number, enrolment number, father's or mother's name, photo, QR code or college name anywhere in your answer.

Return ONLY one JSON object, inside a single ```json code block, with this shape:

{
  "programme": "Bachelor of Commerce",
  "examSession": "May-June 2026",
  "papers": [
    {
      "upc": "2412091101",
      "title": "BUSINESS ORGANISATION AND MANAGEMENT",
      "type": "DSC",
      "semester": 1,
      "credits": 4,
      "gradeL": "A",
      "gradeT": "A+",
      "gradeP": null,
      "finalGrade": "A",
      "gradePoint": 8,
      "creditPoints": 32,
      "status": null
    }
  ],
  "semesters": [
    { "semester": 1, "totalCredits": 22, "totalCreditPoints": 184, "sgpa": 8.36, "cgpa": null, "result": null }
  ]
}

Column guide (marksheet header → JSON field):
- UPC → "upc" (digits only, drop any * mark)
- Paper Title → "title" (copy exactly; keep Hindi titles in Hindi)
- PPT → "type" (e.g. DSC, DSE, GE, GEL, AEC, SEC, VAC)
- SEM → "semester" as a number (I→1, II→2, III→3, IV→4 …)
- CRDT → "credits"
- GR(L) → "gradeL", GR(T) → "gradeT", GR(P) → "gradeP" — use null when the cell is empty
- NTGR → "finalGrade"
- GRPT → "gradePoint"
- CRPT → "creditPoints"
- PPRS → "status" (null when empty, otherwise copy it exactly, e.g. "ER")
- Summary table: SEM → "semester", TTCR → "totalCredits", TTCP → "totalCreditPoints", SGPA → "sgpa", CGPA → "cgpa" (null when empty), RESULT → "result" (null when empty)

Rules:
- One entry in "papers" for EVERY row of the paper table. Do not skip, merge or reorder rows.
- Grades are one of: O, A+, A, B+, B, C, D, P, F. Write "A+", never "A +".
- Numbers must be plain numbers, not strings.
- If a cell is unreadable, use null. Never guess.
- If you are given more than one marksheet, merge all their papers and semesters into the one object.
