The Central Board of Secondary Education (CBSE) is all set to conduct the Class 12, 2024 Physics exam on 4 March 2024. All students, teachers and parents are leaving no stones unturned in Physics Board exam preparation. There’s no denying that hard work and smart preparation is the key to success in this exam, but the way you act in the examination hall and write your exam holds a great importance. It is well observed that many students, though unknowingly, make some common mistakes while writing the Physics Class 12 CBSE board exam. Due to which many students couldn’t score good marks, irrespective of having worked hard to prepare for the exam.
Considering the view of examiners, here we are listing top 10 common mistakes that students make in Physics Class 12 CBSE exam and opens the door for Board examiners to deduct their marks. Read on to ensure that you don’t do these mistakes in your upcoming exam.

- Not keeping a check on the answer word limit
Mostly students have a mindset that longer the answer, more marks will be given to it. This is completely untrue! It is important that the length of the answer should be in accordance to the marks provided for the question. For example, a question of 1 mark should not be answered in a paragraph or an entire page. To improve your writing skills that will lead to good score, you must refer to MTG’s CBSE Champion Book Series aka CBSE Chapterwise Topicwise 10 Years Solved Papers. It gives a complete insight into the latest CBSE marking scheme and guidelines about what needs to be written, what steps to be followed while writing the exam. It has solved question papers of last 10 years CBSE Board Exams along with CBSE Toppers Answers. Give your revision a last few days of strong boost with MTG’s CBSE Champion Book.
- Skipping the units of physical quantities
Students often miss to write the proper units in answers where they are required. Sometimes they are asked to write the answer in a converted unit which they miss due to panic and hurry to finish the exam. Each single unit if missed will lead to a loss of a half mark or more. So, be cautious about it.
- Skipping the formula
Sometimes, even the focused students forget to write the formula while solving the numerical questions. Please note that marks are allotted for writing the formula, not writing it will result in marks deduction even if your answer is correct.
- Confusion in numerator and denominator
Students often flip the numerator and denominator in formulas by mistake. This makes the entire working of the numerical questions incorrect and you get absolutely no marks for the answer. So, you must be thorough with the formulas.
- Error in parallel resistors/ capacitance Formula
A very common mistake students make in the Physics Class 12 CBSE exam is in the formula for finding equivalent resistance in parallel combination.
The correct formula is:
1/R= 1/R1 + 1/R2.
However, students commonly write:
R= 1/R1 + 1/R2.
Same kind of mistake for finding the capacitance. Make sure you avoid these mistakes. You can avoid these by keeping yourself alert and focused in the examination hall. The more you practice the better you get! Solve Sample Papers Released by CBSE for Physics. To practice more and better, you are advised to practice from MTG’s Physics Score More 15 Sample Papers. Sample Papers in this book Series are especially designed on the latest pattern of CBSE Sample Papers, giving you ample questions to practice from!
- Diagram labelling
For diagram questions, it is a must that students label the diagram. To make the paper more presentable and clearer, students should mark these labels in pencil or with a different colour pen.
- Missing out parts of question
In Physics Class 12 CBSE exam, most questions have two or three parts in it, and each part is allocated some marks. Students often tend to overlook or miss out on a small part of the questions, thus losing marks for the same. It would be better if you answer every part in a fresh line or highlight each part of the question.
- Signs conventions error
Signs conventions need to be taken care of especially while solving questions of optics. Also use mirror formula, 1/v + 1/u = 1/f and lens formula 1/v – 1/u = 1/f properly. You can remember these formulas M of mirror for maximum hence it has positive while L of lens for lowest hence it has negative sign.
- Writing wrong question number
This is like a blunder because you know the answer and just because the question number is incorrect, you will lose entire marks. So, make sure you write the correct serial number of the question, even if you answer the last question at the first.
- Duplicity
Sometimes students re-write an answer and forget to strike out the previous one. Please note that if you re-write any answer, strike out the first one. As per CBSE guidelines, examiners are asked to accept the first answer in case of duplicity of an answer.
These are some secret brownie points which will help you to score better in the examination. We hope you will avoid these mistakes in your Physics Class 12 CBSE Exam. Stress and fear are your biggest enemies, maintain a fair distance with them. Stay positive and confident!
Good luck for Physics Board Exams!
