My whole Mathematics script, all 43 pages

The cleanest paper of the five, and the longest booklet — 43 pages, because Maths comes with graph paper bound in. Marked in halves throughout, and the only script where I never attempted both alternatives of an either/or.

Three things are covered, and nothing else

  • · The barcode number on page 1.
  • · The office-use block on the cover — the QR code and the IDEN, BAG and CHK numbers beside it.
  • · The small blue stamp the scanning centre puts on every page.

All three identify the script, not me. Every mark, tick, cross, correction and word of handwriting is untouched — covering those would defeat the purpose.

There was never a name or a roll number to remove. CBSE's own instructions, printed inside the cover and readable on page 3 below, forbid writing your roll number, name or school anywhere in your answers.
