Hello Student,

To crack the UPSC exam as a science student with a PCMB background, start by understanding the exam structure, which includes Prelims , Mains , and an Interview . Begin your preparation by reading NCERT books from classes 6 to 12 for subjects like history, geography, polity, and science.

Next, choose your optional subject carefully. You could opt for science-related subjects like Physics or Chemistry or go for popular options like Geography or Sociology . Develop a daily study plan with time dedicated to current affairs, static subjects, and answer writing practice.

For current affairs , read newspapers like The Hindu and follow monthly compilations. Practice with mock tests and analyze previous years' papers to understand the exam's pattern. Lastly, maintain consistency, and stay motivated through the long preparation journey.

I hope this answer helps you. If you have more queries then feel free to share your questions with us we will be happy to assist you.
