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.

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:

GapYour coverageWhy it matters
Remainders & modular arithmetic2 mentions in 1.03M charsThe single biggest sub-type in the exam — 67 questions, 38% of Number System
Recursive functions f(2n)=f(n)0 mentionsAppears verbatim in real papers
Fermat's little theorem0 mentionsNeeded for large-power remainders
Euler / totient function2 mentionsSame
Integer-solution counting (4x+6y=200)1 mentionRecurring P&C pattern
Symmetric functions of roots5 mentions7% of Algebra
Absolute-value equations5 mentionsRecurring
Para-jumble opening-sentence rule4 mentionsThe 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.

Verbal — only 80 questions, and I do not fully trust the ordering

RankTopicQuestions

2Fill in the Blanks24

4–8Sentence Correction, Error Spotting, Prepositions, Synonyms, Antonyms13

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)

DayMorning (2h)Afternoon (2h)Evening (1h)
1Number System — remainders. Product rule, negative remainders, cyclicity. 01 §1Fermat + Euler for large powers. 01 §1.420 mixed remainder questions
2Number System — digit manipulation, HCF/LCM, factors, trailing zeros, unit digitRecursive functions f(2n)=f(n), base conversion25 mixed Number System
3TSD — trains, relative speed. 01 §2Boats, races, average speed25 TSD questions, timed
4Percentage — marks, inc/dec, concentration, elections. 01 §3Averages — the overlapping-groups trick. 01 §425 mixed
5Profit & Loss + Ratio 01 §5–6Time & Work + pipes 01 §725 mixed

Days 6–8 · Numerical Tier 2

DayMorning (2h)Afternoon (2h)Evening (1h)
6Probability — cards, dice, balls. 02 §1P&C — committees, circular, integer solutions. 02 §225 mixed
7Algebra — quadratics, symmetric functions, modulus. 02 §3Mensuration — circle, cube, cylinder. 02 §425 mixed
8Mixture & alligation (replacement formula), Ages, Geometry. 02 §5–7SI, CI, Clocks, DI, Progressions — skim only. 03Full Numerical mock, 1 hour

Days 9–10 · Logical

DayMorning (2h)Afternoon (2h)Evening (1h)
9Seating (circular + linear), Blood Relations. 04 §1–2Coding-Decoding — letter-shift drilled hard. 04 §320 puzzles, timed
10Direction Sense, Series, Syllogism. 04 §4–6Cubes & Dice, Analogies, Statement-Conclusion. 04 §7–9Full Reasoning mock

Days 11–12 · Verbal

DayMorning (2h)Afternoon (2h)Evening (1h)
11Cloze passages — the real shape of TCS verbal. 05 §1Fill in the blanks, connectors, tense. 05 §230 min on tcs.com reading their blog (see below)
12Para jumbles, error spotting, sentence correction. 05 §3–5Vocabulary — your own 286-synonym / 275-antonym banksFull Verbal mock

Days 13–14 · Consolidation

DayPlan
13Full-length mock in exam conditions. Then spend the entire afternoon on your errors — not on new topics. Evening: formula sheet 06.
14No 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 revision

Rule: 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 ABILITY is 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.

These three are ~20% of the word count and are not study material. They exist so you can check my working and see where the notes came from. Do not read them during your 14 days beyond a single pass over 08 — that one contains the exam-rule changes that affect your strategy.


Start here, in this order

  1. Read 15 - REAL CANDIDATE REPORTS 2026 — real students, June–July 2026. It corrects three things in these notes: sentence completion has no options, SI/CI is a top topic, and coding now includes trees/heaps/BFS. 20 minutes, highest priority.
  2. Read 08 once — no negative marking, locked navigation. 15 minutes.
  3. Read this file's plan above.
  4. Open 11 - DAILY DRILL MAP and set up Day 1.
  5. Go to 01 §1.1 — remainders. That is where the most marks are sitting.
