The Central Board of Secondary Education (CBSE) is all set to commence the Class 12, 2019 Physics exam on 7 March 2019. All students, teachers and parents are leaving no stone 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 exam. Due to which many students couldn’t score good, irrespective of having worked hard to prepare for the exam.
Considering the view of examiner, 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 Keep 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. It gives a complete insight into 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. Give your revision of last few days a strong boost with

- 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 intelligent 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 right.
- Confusion in Numerator and Denominator
Students often flip the numerator and denominator in formulae 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 through 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

- 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 question, thus losing marks for the same. It would be better if you answer every part in a fresh line or highlight the answers of every 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 question number 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.
Indeed, these are some treasured points 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!
