Author’s Expert Tips
- Attempt the General Aptitude section first if you’re faster there — it builds confidence before the tougher Domain Knowledge section
- For the Law Officer domain paper, build one-page summary notes per Act rather than reading full bare Acts repeatedly
- Since negative marking is 0.25, skip questions where you can’t eliminate at least two options
- Practice previous PSU law officer domain papers (Oil India, IBPS SO) for pattern familiarity — the concepts overlap even if the exact syllabus differs
- Register early; portals frequently slow down in the last 48 hours before the deadline
- Keep your three CBT centre choices geographically realistic to avoid last-minute travel stress
- Revise current developments in petroleum-sector regulation, since PSU law officer papers often test sector-specific legal awareness
