- Build technical basics: The 100-question Technical Abilities section in CBT 2 is decisive; revise core subjects from your diploma/B.Tech notes.
- Practise previous year papers: Solve RRB JE papers of earlier CEN cycles (01/2019, 03/2024) under timed conditions.
- Focus on accuracy: With 1/3 negative marking, avoid blind guessing and attempt sure questions first.
- Take mock tests: Attempt full-length mocks for CBT 1 and CBT 2, analyse mistakes and track sectional accuracy.
- Daily current affairs: Read railway, science and environment news of the last 12 months.
- Revise formulas: Keep formula sheets for Mathematics, Physics and Chemistry and revise them regularly.
- Time management: In CBT 2, give about 70-80 minutes to the Technical section and the rest to general sections.
- Keep documents ready: Document Verification is strict; keep all certificates organised.
