How to Write Board Exam Answers That Score Full Marks (CBSE & ICSE)

Most students lose marks not on what they know, but on how they write it. Here is how examiners read an answer, and how to write one that earns every mark.

Every year, students in Kharghar tell us after their prelims: “I knew the answer, but I still lost marks.” The reason is almost always the same. Board examiners mark what is written on the page, in the time they have, against a marking scheme. An answer that hides its key points, skips steps or wanders off the question loses marks even when the student understands the topic.

The good news is that answer-writing is a skill. It can be practised, and it improves quickly. These are the habits we teach our CBSE and ICSE students in the months before the board exams.

1. Read the question twice, and answer what is asked

  • Underline the command word: define, explain, compare, justify, calculate, draw. Each asks for a different kind of answer.
  • Check the marks: a 1-mark question needs one precise point; a 3-mark question usually needs three.
  • Answer the exact question: writing everything you know about a topic does not earn marks for the part that was asked.

2. Make every point easy to find

  • Start with a direct answer in the first line, then explain.
  • Use short paragraphs or points for longer answers, one idea per point.
  • Leave a line between answers and write the question number clearly in the margin.
  • Underline keywords and final answers, sparingly, so they stand out.

3. In Mathematics and Science, show every step

In numerical and derivation questions, marks are usually given for steps, not just the final answer. Write the formula, substitute the values with units, then calculate. If you make a small error near the end, the steps above it can still earn most of the marks. A correct answer with no working may not.

  • Write the given data and what is to be found.
  • Always include units, and box the final answer.
  • In geometry, give a reason for every statement.

4. Use diagrams where they help

In Science, Geography and Biology, a neat, labelled diagram often earns marks on its own and saves words. Draw in pencil, label clearly with straight lines, and give the diagram a title. Practise the standard diagrams from each chapter until you can draw them quickly.

5. Use the subject's own language

Examiners look for the correct terms: “displacement”, not “distance moved”; “photosynthesis”, not “making food”; the correct names of processes, laws and parts. Make a list of the key terms in each chapter and use them in your answers. In English and the humanities, write in complete, clear sentences and support points with examples.

6. Plan your time before you start

  • Use the reading time to choose the order in which you will attempt the sections.
  • Divide your time by marks, and keep the last 10–15 minutes to review the paper.
  • If you are stuck, leave space and move on. Come back later instead of losing time on one question.
  • Never leave a question blank. A partly correct answer can still earn marks.

7. Practise full papers, and learn from the checking

Answer-writing improves only when someone checks your answers the way an examiner would and shows you where marks were lost. Write full papers in the real exam time, have them checked, and keep a list of your repeated mistakes to revise before the next paper. This is exactly how our Test Series and Board Exam Crash Course work. For official papers, use the CBSE sample papers on cbseacademic.nic.in and the ICSE specimen papers on cisce.org.

Frequently asked questions

Do neat answers really get more marks?

Examiners mark content, not handwriting, but a clearly laid-out answer makes it easy for them to find every point they are looking for. Untidy, crowded answers make it easy to miss a step or a keyword.

Should I write long answers to get more marks?

No. Write what the marks ask for. A 2-mark answer needs two clear points, not a page. Long answers waste time you need for the rest of the paper.

How many full practice papers should a Class 10 student write?

Aim for at least one full paper per subject every week from January, written in the real exam time, and checked so you can see where marks were lost.

Is answer-writing different for CBSE and ICSE?

The habits are the same, but ICSE usually expects longer written answers, especially in English and the humanities, while CBSE includes more competency-based and case-based questions. Practise with each board's own sample and specimen papers.
