Can I do rough in any paper in board exam

No, in CBSE board exam or any board exam, you cannot do rough work on just any paper. They usually provide extra space in the answer sheet, or students can use the last page for rough work (if allowed).

In board exams, rough work should be done in the space provided in the answer sheet or on the last pages if allowed. You cannot use separate sheets unless permitted by the exam authorities. It’s important to keep rough work neat and ensure it does not interfere with your final answers. Always follow the guidelines set by your board to avoid any issues during evaluation. If unsure, ask the invigilator for clarification.
