Expression, presentation and language accuracy
These marks are not a reward for beautiful handwriting, but they are steadily lost through avoidable presentation errors. An examiner works through a large pile of copies; an answer that is easy to mark scores more of what it knows. Presentation is therefore a scoring skill, not decoration.
Rules that pay
- Number answers exactly as they appear on the question paper, including sub-parts (a), (b), (c); a misplaced answer can be marked absent.
- Start each answer on a new line, underline the key technical term once, and keep one idea per bullet.
- For diagrams: pencil and ruler, labels horizontal, title below, and a minimum size of about a quarter page.
- Respect word limits - roughly 30 words for very short answers, 50 for short, 75–100 for long ones.
- Keep one medium throughout; a prescribed technical term may stay in English inside a Hindi answer.
- Close long answers with a single concluding line that answers the command word.
Worked example
Before: "Pollution is very bad. It harms everyone. We should stop it." After: "Pollution is the addition of harmful substances to a natural resource beyond its capacity to absorb them. Two named causes are industrial effluent and vehicle exhaust. Two effects are… The remedy is…" The reasoning: each vague sentence has been converted into one scorable unit - definition, named causes, effects, remedy - inside the same word limit.
Traps that cost marks
One-block paragraphs with no visible structure; mixing scripts or mediums mid-answer; unlabelled diagrams; SMS spellings of technical terms; and overlong early answers that leave the final question unattempted.
