Most candidates need 4–8 weeks of focused preparation for TCS NQT. The exam rewards speed and pattern recognition over deep theory, so the right strategy is: learn the question types, drill previous-year questions, then simulate the real test.
A 6-week plan that works
- Weeks 1–2 — Foundation basics: Cover the core aptitude formulas (percentages, interest, time-work, ratios), grammar rules and the standard reasoning types. Solve 20–30 questions daily.
- Weeks 3–4 — Topic depth + coding: Move to the advanced-section topics and start daily coding practice — one array or string problem a day in your chosen language, always reading input exactly as specified.
- Weeks 5–6 — Papers and mocks: Switch entirely to previous-year papers and timed mock tests. Review every wrong answer the same day.
Section-wise tactics
- Numerical: memorise fraction-percentage equivalents (1/8 = 12.5% etc.) and squares up to 25 — they cut solving time in half.
- Verbal: read one editorial daily and practice para jumbles by finding the opening sentence first.
- Reasoning: practice series and coding-decoding to under 45 seconds each; draw quick diagrams for arrangements.
- Advanced coding: solve past TCS problems end-to-end including I/O handling — see Advanced Coding for real examples with solutions.
In the exam hall
- No negative marking — answer everything, guess if needed.
- Sections are locked and individually timed; never leave a section with time unused.
- Attempt the easier coding problem first and secure full test-case marks.
