Hii!

The eligibility criteria for UPSC exam states that the candidate must have completed graduation degree with minimum 50% marks in a relevant subject discipline from a recognised university.

To prepare for the exam, you must know the syllabus well, and start with the subjects you are confident in. This will help you gain motivation and push you to study more. Then, go for tough subjects. Also, read general knowledge and current affairs and newspapers daily.
