Students often lose marks because of small mistakes. In the Physics board exam, writing too much or too little can cost you time and marks. For example, writing a whole page for a one-mark question will still give you only one mark. Always keep your answer length appropriate for the marks. Write short, precise answers for small questions, and give full steps for longer ones.

Answering Questions Carefully

• Write the exact answers by marks: Don’t write too much for 1-2 mark questions. Keep short answers crisp—about 2–3 lines for 2 marks and more for longer questions.

• Show all steps in numericals: Always write the formula you use and include the units. Marks are given for showing the correct working. If you skip the formula, you can lose points. Double-check that units like meters per second squared (m/s²) or kilograms (kg) are correct.

• Be careful with values in calculations: For example, in parallel circuits, the total resistance is 1 divided by total resistance, which equals 1/R1 plus 1/R2. Many students write it incorrectly as total resistance equals 1/R1 plus 1/R2—this is wrong. Always write formulas carefully and check them before solving.

Diagrams and Labelling

In Physics, diagrams are important. Draw a clear and simple sketch, and label all the parts. Make sure arrows and lines are easy to read so the examiner can understand your answer. A neat, labeled diagram can help you get extra marks.

Exam Strategy and Time Management

Time management is vital. Do not spend too long on any one question. First answer easier questions. Keep an eye on the clock and allocate about 6–7 minutes per 10-mark question. Check that you have written the correct question number for each answer; a wrong number means no marks.

Answer every part of multi-part questions to avoid losing bits of marks. For “Yes/No” or value-based questions, always give a reason or explanation (even 1-mark questions require a short reason).

Practice with Mock Tests and Past Papers

Good preparation is important in avoiding mistakes. Make sure you cover the CBSE Class 12 syllabus completely so nothing surprises you in the exam. Solve past papers and sample questions to get the actual feel for the exam. Taking a Class 12 Physics Mock Test under timed conditions can show you exactly where you go wrong. After each test, check your mistakes, focus on weak areas, and practice them again. Doing this regularly will make you faster, more confident, and ready to tackle the real exam with ease.

Final Thoughts

Remember, mock tests are supplements—they help you to get the idea of the actual exam. But also study theory deeply; don’t rely on them entirely. After each test, analyze mistakes: this stops you from repeating them in the board exam. By avoiding these errors and practicing well, you can boost your Physics score significantly.
