START HERE — Your 14 Days
You already own a library. What you were missing is a route through it.
You have 84 study files (~1.03 million characters) across files/ and Aptitude Study Material/. They are good. But they are flat — every topic gets similar weight, and nothing tells you what to do on Day 1 versus Day 11.
These notes are the prioritisation layer. They tell you what to study, in what order, how deep to go, and — just as importantly — what to skip.
What this is built on
| Evidence | What it gave me |
|---|---|
| 11 real TCS exam papers | topic frequency, mapped to dated slots (Aug 2023) |
| Arjunpolen TCS-NQT-PYQ repository | repeat detection |
/TCS folder + Placement Lelo books | ~1,153 additional questions |
| 1,401 classified questions | sub-type frequencies inside each topic |
| Coverage audit of your 84 existing files | the gaps below |
The audit found real holes in your existing material
I checked your 84 files against the high-value sub-types. Most are well covered. These are not:
| Gap | Your coverage | Why it matters |
|---|---|---|
| Remainders & modular arithmetic | 2 mentions in 1.03M chars | The single biggest sub-type in the exam — 67 questions, 38% of Number System |
Recursive functions f(2n)=f(n) | 0 mentions | Appears verbatim in real papers |
| Fermat's little theorem | 0 mentions | Needed for large-power remainders |
| Euler / totient function | 2 mentions | Same |
Integer-solution counting (4x+6y=200) | 1 mention | Recurring P&C pattern |
| Symmetric functions of roots | 5 mentions | 7% of Algebra |
| Absolute-value equations | 5 mentions | Recurring |
| Para-jumble opening-sentence rule | 4 mentions | The core technique of the topic |
So these notes go deep on exactly those, and act as a prioritised index for everything already covered well. I am not going to re-write Pipes & Cisterns when you have 86 mentions of it already.
The honest picture of what matters
Sub-type shares are within their topic. Topic size is what decides your hours.
Numerical — 1,214 questions in the corpus
| Rank | Topic | Questions | The sub-types that actually appear |
|---|---|---|---|
| 1 | Number System | 175 | Remainders 38%, digit-manipulation 11%, HCF/LCM 5% |
| 2 | Time Speed & Distance | 140 | Trains 16%, relative speed 16%, boats 11%, races 9% |
| 3 | Probability | 93 | Cards 27%, dice 25%, balls 18% |
| 4 | Percentage | 89 | Marks/pass-fail 19%, inc/dec 15%, concentration 13%, elections 10% |
| 5 | Equations & Algebra | 85 | Quadratics 37%, symmetric functions 7% |
| 6 | Permutation & Combination | 82 | Committees 13%, distribution 11%, circular 6% |
| 7 | Averages | 82 | Overlapping groups 17%, ages 12%, marks 12% |
| 8 | Profit & Loss | 70 | Basics 56%, marked price 17% |
| 9 | Mensuration | 67 | Circle 28%, cube 16%, cylinder 16% |
| 10 | Time & Work | 64 | Combined rate 44%, efficiency 17%, pipes 11% |
| 11 | Ratio & Proportion | 54 | Variation 19%, dividing a sum 11% |
| 12 | Geometry | 40 | Triangles 43%, angles 18% |
| 13 | Ages | 33 | Father–son 42%, ratio 12% |
| 14 | Mixture & Alligation | 28 | Replacement 46%, alloys 21% |
| 15 | Clocks & Calendars | 27 | Angle, coincide, day-of-week |
| 16–20 | SI, CI, Statistics/DI, Progressions, Partnership | 85 total | light |
Logical — 107 questions
| Rank | Topic | Questions | The concentration |
|---|---|---|---|
| 1 | Seating Arrangement | 23 | circular 39%, linear 39% |
| 2 | Coding-Decoding | 23 | letter-shift 74% — the most concentrated topic in the exam |
| 3 | Blood Relations | 20 | direct chain 65%, coded 35% |
| 4 | Direction Sense | 11 | distance-from-start 45%, turns 45% |
| 5 | Number/Letter Series | 9 | next term 67% |
| 6–11 | Analogies, Syllogism, Statement-Conclusion, Cubes & Dice, Venn, Puzzles | 21 total | light |
Verbal — only 80 questions, and I do not fully trust the ordering
| Rank | Topic | Questions |
|---|---|---|
| 1 | Reading Comprehension — but mostly CLOZE passages | 34 |
| 2 | Fill in the Blanks | 24 |
| 3 | Para Jumbles | 9 |
| 4–8 | Sentence Correction, Error Spotting, Prepositions, Synonyms, Antonyms | 13 |
Verbal caveat, stated plainly. Only 80 questions survived extraction versus 1,214 Numerical, and 35% of them did not classify. Synonyms and Antonyms show 1 question each purely because your vocabulary banks are stored as word lists, not questions — they hold roughly 286 synonyms and 275 antonyms and you should absolutely not skip them. Treat this ordering as a hint.
The 14-day plan
Assumption: ~5 hours a day. Scale proportionally if you have more or less. Every day ends with a 20-minute review of that day's errors — that review is not optional, it is where the improvement actually happens.
Days 1–5 · Numerical Tier 1 (the 60% that carries the section)
| Day | Morning (2h) | Afternoon (2h) | Evening (1h) |
|---|---|---|---|
| 1 | Number System — remainders. Product rule, negative remainders, cyclicity. 01 §1 | Fermat + Euler for large powers. 01 §1.4 | 20 mixed remainder questions |
| 2 | Number System — digit manipulation, HCF/LCM, factors, trailing zeros, unit digit | Recursive functions f(2n)=f(n), base conversion | 25 mixed Number System |
| 3 | TSD — trains, relative speed. 01 §2 | Boats, races, average speed | 25 TSD questions, timed |
| 4 | Percentage — marks, inc/dec, concentration, elections. 01 §3 | Averages — the overlapping-groups trick. 01 §4 | 25 mixed |
| 5 | Profit & Loss + Ratio 01 §5–6 | Time & Work + pipes 01 §7 | 25 mixed |
Days 6–8 · Numerical Tier 2
| Day | Morning (2h) | Afternoon (2h) | Evening (1h) |
|---|---|---|---|
| 6 | Probability — cards, dice, balls. 02 §1 | P&C — committees, circular, integer solutions. 02 §2 | 25 mixed |
| 7 | Algebra — quadratics, symmetric functions, modulus. 02 §3 | Mensuration — circle, cube, cylinder. 02 §4 | 25 mixed |
| 8 | Mixture & alligation (replacement formula), Ages, Geometry. 02 §5–7 | SI, CI, Clocks, DI, Progressions — skim only. 03 | Full Numerical mock, 1 hour |
Days 9–10 · Logical
| Day | Morning (2h) | Afternoon (2h) | Evening (1h) |
|---|---|---|---|
| 9 | Seating (circular + linear), Blood Relations. 04 §1–2 | Coding-Decoding — letter-shift drilled hard. 04 §3 | 20 puzzles, timed |
| 10 | Direction Sense, Series, Syllogism. 04 §4–6 | Cubes & Dice, Analogies, Statement-Conclusion. 04 §7–9 | Full Reasoning mock |
Days 11–12 · Verbal
| Day | Morning (2h) | Afternoon (2h) | Evening (1h) |
|---|---|---|---|
| 11 | Cloze passages — the real shape of TCS verbal. 05 §1 | Fill in the blanks, connectors, tense. 05 §2 | 30 min on tcs.com reading their blog (see below) |
| 12 | Para jumbles, error spotting, sentence correction. 05 §3–5 | Vocabulary — your own 286-synonym / 275-antonym banks | Full Verbal mock |
Days 13–14 · Consolidation
| Day | Plan |
|---|---|
| 13 | Full-length mock in exam conditions. Then spend the entire afternoon on your errors — not on new topics. Evening: formula sheet 06. |
| 14 | No new material. Revise 06 formula sheet + 07 last-48-hours file. Light 20-question warm-up. Sleep early. |
The single strangest edge you have
Spend 30 minutes on tcs.com the week before.
My analysis found that TCS's cloze passages are written from TCS's own blog and marketing content — one extracted passage is literally tagged "cloze passage source: tcs leader ashok pal wrote in his blog", and the surrounding text is about digital transformation. Reading a few of their thought-leadership posts familiarises you with the exact vocabulary and register the passages use.
No coaching site will tell you this. It costs you half an hour.
What to deliberately skip
Skipping is a strategy, not laziness. With 14 days, these are low return:
- Partnership (6 questions) — one formula, learn it from the sheet, move on
- Logarithms (1 question) — skim the identities only
- Venn diagrams, Puzzles (1 each) — read the method once
- Trapping Rain Water and other hard DSA — irrelevant to aptitude
- Deep geometry proofs — you need formulas and Pythagorean triples, not derivations
- Anything you have never seen before on Day 12 or later — new topics that late cost more than they return
How to use these notes with your existing files
These notes (TCS-14-DAY-NOTES/) → prioritised method, shortcuts, traps, gaps filled
↓ when you need more practice on a topic
files/<Topic>-TCS-NQT-Complete-Study-Material.md → full theory + practice sets
files/<Topic>-Important-Questions-with-Solutions... → worked solutions
Aptitude Study Material/<nn> - <Topic>.md → sub-type walkthroughs
files/TCS-NQT-2026-MASTER-FORMULA-SHEET-All-Topics.md → night-before revisionRule: read the note here first, and only open the big file if the note tells you to or you need more drilling.
Exam-day facts — now confirmed by the 2026 research
Details and sources in
08 - ONLINE RESEARCH FINDINGS.md. Read that file — it settles four things I had previously hedged on and adds two topics I had missed.
- ✅ NO negative marking in 2026 (confirmed by three sources — previously I told you this was disputed). → Never leave a question blank. Fill everything in the last 60 seconds of each section.
- ✅ You cannot return to a question once answered, and cannot switch between sections. → There is no "flag and come back". Commit, then move. Do not budget time for a review pass.
- ✅ Verbal has genuinely changed: ~20 Sentence Completion + 4 Passage Recall + 1 Professional Email, ~26 minutes. → Your file
16 - VERBAL ABILITYis built on exactly this and is correct. I was wrong to hedge on it. - ✅ Advanced Coding is 90 minutes, 2 problems.
- ⚠️ Two reasoning topics my corpus analysis missed — Data Sufficiency and Figure/Non-verbal Series. Both are now in
04. - ⚠️ Section question-counts and timings conflict across sources. Plan on ~90 seconds per question and read the real numbers off the instruction screen.
- 🎯 Reported cutoffs: Ninja ≈ 18/30, Digital ≈ 22/30 — roughly 60% and 73%. You do not need to be perfect.
- Do not trust prep-site answer keys blindly. I found demonstrable errors in them during the analysis.
