Hi,

If  you belong to Humanities stream, you can begin with reading your own NCERT textbooks in details. The core basic of the UPSC CSE is started by reading the NCERTs to form a strong base. Even if you belong to other streams, at this phase, you can begin with just reading newspaper. It may appear to be simple, but, when you will start reading newspaper in your UPSC preparation, newspaper alone will take 2-3 hours to get the details. Read The Hindu and The Indian Express, slowly you will develop pace and can identify the important topics to be read. It can save your further time. Right now, just focus on your class 11 and 12 studies. If we see, it will be too early to prepare for the exam. UPSC prepares the syllabus accordingly and it will take a maximum of two years to complete the comprehensive syllabus including both Mains and Prelims. So, right now you can focus on your studies and can begin with newspaper reading.
