TCS NQT is not only about “knowing topics” — it’s about speed + accuracy + consistency.
This guide gives you a high-impact preparation system for Aptitude and Coding, with clear daily actions
that help you improve score predictably (especially if you’re targeting Digital/Prime).
🧠 1) The Right Strategy Mindset (Most Important)
Focus on “Score ROI” topics first
In Aptitude, you don’t need to master everything. Start with topics that give quick marks:
Percentages, Ratio, Averages, Time & Work, Time & Distance, DI basics.
Percentages, Ratio, Averages, Time & Work, Time & Distance, DI basics.
Accuracy > Attempt count
Many candidates fail because they rush. Keep a target: 85–90% accuracy in practice.
When accuracy rises, speed automatically improves with repetition.
When accuracy rises, speed automatically improves with repetition.
Daily rhythm (minimum)
90 minutes/day is enough if you’re consistent:
45 min Aptitude + 45 min Coding + 10 min error-review.
🧮 2) Aptitude Tips That Actually Improve Score
A) Use “Formula + Pattern + Timed Drills”
- Formula: Write formulas once in your own notes (not screenshots).
- Pattern: Identify common patterns (mixtures, speed change, work efficiency).
- Timed drills: Solve 15–20 questions in a fixed time block (like exam pressure).
B) Most Scoring Aptitude Topics (Start Here)
Percentages → Profit & Loss → Ratio → Averages → Time & Work → Time & Distance → DI
These topics connect. Mastering them boosts multiple question types.
C) DI hack (Data Interpretation)
DI is about speed. Practice:
approximation, ratio comparison, and quick % change.
Don’t over-calculate. Use elimination where possible.

D) Your “Error Notebook” will beat any course
Maintain a single note page with:
✅ topic name, ✅ wrong step, ✅ correct logic, ✅ shortcut
Revise it every 3 days. This alone can add 15–25% improvement.
Aptitude time management rule
If you can’t see a path in 25–35 seconds, mark it and move on.

💻 3) Coding Tips for TCS NQT (Logic + Implementation) Exam Question & Answers
A) Follow a fixed problem-solving workflow
- Read constraints carefully (input size decides approach).
- Write 2–3 sample cases (including edge cases).
- Plan brute force first, then optimize.
- Code with clean functions + meaningful variables.
- Dry-run quickly before submit.
B) What to practice daily (high frequency topics)
- Strings: frequency count, palindrome, anagram, substring patterns
- Arrays: prefix sums, two pointers, max/min subarray
- Math: gcd/lcm, primes, modulo basics
- Searching/Sorting: binary search, custom sort logic
- Basic DS: stack/queue usage (balanced parentheses, next greater element)
C) Avoid these common coding mistakes
- Forgetting edge cases (empty array, single element, large input)
- Not handling input format exactly (spaces/newlines)
- Using O(n²) when constraints need O(n log n) or O(n)
- Not checking overflow / using correct data types
D) The easiest way to level up to Prime/Digital
Along with coding, revise fundamentals:
OOPS, DBMS (SQL joins, keys, normalization),
OS basics, and CN basics.
Many candidates ignore these and lose interview confidence.

🧪 4) Mock Test Strategy (This is where rank improves)
- Mock frequency: 2 mocks/week initially → 4 mocks/week in last 10 days.
- Mock review time: Spend 2× the mock duration on analysis (critical).
- Classify mistakes: Concept gap / silly error / time management.
- Fix loop: Convert every mistake into 3 similar practice questions.
- Section timing: Start with your strongest section to build momentum.
Golden rule
Your score doesn’t improve by doing more mocks — it improves by doing better analysis of mocks.
📅 30-Day Preparation Plan (Simple + Effective)
Daily minimum routine (90 minutes)
45 mins Aptitude (timed sets) + 45 mins Coding (1–2 problems) + 10 mins analysis.
Consistency beats long weekend studying.

❓ FAQ – TCS NQT Preparation
How many hours per day are enough for TCS NQT?
If you’re consistent, 1.5 to 2 hours/day is enough for 30 days. Increase to 3 hours/day in the last 7–10 days with mocks + analysis.
What is the best way to improve speed in aptitude?
Use timed drills (15–20 questions/set), maintain an error notebook, and repeat weak topics every 3 days.
How many coding problems should I solve daily?
Minimum: 1 problem/day. Ideal: 2 problems/day (one easy-medium + one logic/DSA based). Always re-solve your wrong solutions.
How can I target Digital/Prime roles?
Keep strong coding consistency + revise OOPS, DBMS, OS, CN basics. Also focus on mock analysis and writing clean code with correct edge-case handling.
