NCERT books are known for their comprehensive content and simplicity. Begin your preparation by thoroughly studying the NCERT books of subjects such as History, Geography, Polity, Economics, and Science. These books provide a clear understanding of the fundamental concepts, which is crucial for cracking the UPSC exam.

2. Read line by line:
While studying NCERT books, it is important to read every line attentively. Do not skip any portion, as UPSC questions are often derived from the minutest details mentioned in these books. Pay close attention to examples, illustrations, and diagrams as they help in better comprehension and retention.

3. Make notes:
While studying NCERT books, make concise notes of important topics, facts, and figures. This will help in quick revision during the exam. Highlight or underline key points to make them stand out while revising. Organize your notes subject-wise for easy access.

NCERT books contain a variety of exercise questions at the end of each chapter. Solve these questions to test your understanding of the concepts. This practice will enhance your problem-solving skills and familiarize you with the type of questions asked in the UPSC exam.

5. Refer to additional resources:
While NCERT books cover the basics, it is also essential to supplement your preparation with other reference books, online resources, and current affairs materials. These additional resources will provide a broader perspective and help you stay updated with recent developments.

6. Revise regularly:
Consistent revision is the key to retaining information. Allocate regular time slots for revisiting the NCERT books and your notes. This will reinforce your understanding of the concepts and improve your retention power.

7. Practice previous year question papers:
In addition to studying the NCERT books, practicing previous year question papers is crucial for understanding the exam pattern and gaining familiarity with the type of questions asked. Analyze your performance and identify areas where you need to focus more.
