Hi student,

UPSC examination is one of the toughest entrance examinations in the country. It takes years of preparation for some while only one year for others. It totally depends on the individual. As far as success ratio is concerned, it is eight lakhs of students competing for a few hundred seats. Moreover, its vast and diverse syllabus makes it more difficult. The seats for UPSC examination including all the posts like IAS, IPS, IFS, IT, group A and group B services etc is around 1200. So you need atleast one year of preparation to qualify for UPSC.

Hope it helps.

Good luck.
