Hello,

First of all in order to initiate your preparation you need to be well acquainted with the exam pattern and syllabus, UPSC is conducted in three stages namely Prelims, Mains and Interview.

To provide you a brief about the exam;

Preliminary: First Stage is MCQs based exam, it has two papers and each one consists of 200 marks,its numbers ain't added to final list, you just need to score the required cut offs against your category. First is GS Paper-I which consists of the following topic such as History of India and Indian national movement, Indian and World geography, Economic and social development- sustainable development, poverty,inclusion demographics, social sector initiatives etc,Indian polity and governance-constitution,political system,Current Events nationally and Internationally, General Science,General Issues on environmental ecology,biodiversity and climate change. you just need to score the required cut offs against your category.

The last stage is interview for 275 marks.

Secondly, newspaper reading is very vital for this exam, hence make a habit of reading the same on daily basis, you can start off with The Hindu or The Indian Express. put more emphasis on editorials, news of national and international importance, government policy and scheme, science and technology, economics etc. when it comes to study materials start off with NCERTs as this will make your base strong, in UPSC exam it's imperative to have at least the basic knowledge of all the subjects, you don't have to be an expert, but you must have a decent understanding of the subjects so that you can write it down in Mains.
