How to prepare for UPSC ESE
A good UPSC ESE plan combines concept study, topic-wise practice and regular full-length mock tests. Use the checklist below as a starting point.
- Your GATE preparation overlaps heavily with the Prelims discipline paper.
- Practise conventional answer writing for the Mains.
- Do not ignore the General Studies paper, which can decide cut-offs.
- 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.
