# Important Chapter of RD Sharma for CBSE students Class 12?

RD Sharma is one of the best reference materials after the NCERT. It is a very important and prominent math book to achieve maximum marks in the examination.

Solving maths problems is interesting for many, while others find cold feet. Math is a scoring subject in comparison to other subjects of class 12.

To make a clear understanding of each topic, students must have to go through the concepts carefully.

Indeed, you cannot score 100 out of 100 by studying an important chapter. You have to go the extra mile. But surely you can score 90+, which also comes in the category of excellent marks.

By analyzing the syllabus and previous trends of the examination under the expert’s guidance, we have provided the important chapters of RD Sharma for CBSE class 12.

**Important topper tip: **You don’t have to prove to anyone how much knowledge you have in your mind. You just have to score maximum marks in the examination. So combine your hard work with smart work.

Don’t start solving any questions blindly. Analyze the previous year’s paper and marks the topic into your syllabus. Give proper practice time to each marked topic and revise them properly. To save you time, you can check the **Important questions for class 12 maths****. **
