About the UPSC exam
UPSC Civil Services Examination (IAS, IPS, IFS) is one of the better-known exams in India. It is administered by Union Public Service Commission (UPSC) and attracts a large number of candidates each cycle. The exam is held once a year, with Prelims usually held in May or June.

How to prepare for UPSC
A good UPSC plan combines concept study, topic-wise practice and regular full-length mock tests. Use the checklist below as a starting point.
- Build your base with NCERTs and one standard Polity text, then layer current affairs from the last 12 to 18 months on top.
- Attempt a full-length timed Prelims paper every week and note how many answers you were sure about versus guessed, because negative marking punishes blind guessing.
- Practise CSAT passages and basic numeracy regularly so the qualifying paper never becomes a last-minute risk.
- Analyse every mock test: separate errors into concept gaps, calculation slips and time pressure, and fix one group at a time.
- Keep a short error notebook and revise it weekly, since repeated mistakes cost more marks than new ones.
