Physics is one of the most scoring CBSE Science subject in Board Exams. So, students need to answer all the questions very carefully. Any silly mistake will result in losing the marks.

Here we have made a list of all the common mistakes which students make while writing their CBSE Physics Board Exam:

For a 1 mark question, the answer should not be of more than 20 words. For two marks question, you can write it in half a page. For four marks question, a page will be enough.

Formulae are the backbone of Physics. So, it’s important that you write the correct formula. The most common formula that CBSE Class 12th students often forget is:

Finding Capacitance in Series

The formula is: 1/c= 1/c1 + 1/c2

Students write: c= 1/c1 + 1/c2

Students should label the diagrams carefully and neatly, preferably with a pencil. Many students often make a mistake of not labeling the diagram properly which results in losing their marks. So, all students must take care of it.

While answering the value-based questions, students should write their answers in 3-4 sentences, not in a single sentence. As this will increase the chances of getting full marks.

In CBSE Physics Board Exam, there are many questions which have several parts. Each part is provided with some marks. So, don’t miss out any part as you will lose some marks.

For “Yes” or “No” type questions, students should also mention the reason behind writing “Yes” or “No” as this will help them get full marks for that answer.

All the laws should be written as they are stated. Don’t reframe the statement or don’t write only the mathematical expression. Marks are given to the statement of law only.
