Hey student,

The Civil Services Examination is a nationwide competitive examination in India conducted by the Union Public Service Commission for recruitment to higher Civil Services of the Government of India, including the Indian Administrative Service, Indian Foreign Service, and Indian Police Service.

If you want to crack this exam without coaching with your own you'll definitely need youtube as it will provide you alot of lectures and tips. You need to study Atleast 7-8 hours and revise everything at the end of the day. Take a break to reduce stress and this will help you crack upsc without a coaching.

All the best student,

Hope this helps you.
