The problem

Twenty weeks. Eleven subjects. Most of them unequal.

Spending your weeks in proportion to the syllabus is not the same as spending them in proportion to the evidence. Some topics have been examined in almost every recent paper. Several have not appeared in a decade. Both facts are knowable from the archive, and almost nobody checks.

37 papers, not opinions

Every GATE CS paper and set from 2000 to 2026, analysed for marks per subject and for which concept was tested in which year and format.

An eight-factor model

Long-term frequency, recent frequency, concept breadth, syllabus centrality, time since last appearance, format fit, organiser signal, and other evidence. The weights are published, not hidden.

The 2027 revision, mapped

The official syllabus PDF was extracted and compared word by word with 2026. Three sections changed. One of them changed a lot.

Study plan · from today to the exam hall

Exactly what to study, week by week

The book does not just predict topics. It tells you what order to study them in: the highest-mark subjects first, then practice, then all ten mock tests at the real exam time. Pick the route that matches the time you have left.

Tue 15 Sep 2026 · week 1Sat 6 Feb 2027 · first exam day
Phase 1Weeks 1–9 · 15 Sep – 15 NovFinish concepts, in order of marks
  • One subject a week: Maths (two weeks), Programming & DS, Algorithms, OS, COA, Computer Networks, then TOC with DBMS, then Compiler Design with Digital Logic
  • Priority A concepts to exam standard; Priority B covered once
  • General Aptitude, 20 minutes every day
In the book: subject chapters, Top 100 concepts
Phase 2Weeks 10–13 · 16 Nov – 13 DecPrevious-year papers and the question bank
  • Topic-wise PYQs, 2014–2026 first, skipping topics removed in 2027
  • The book’s question bank, two subjects a week
  • Mocks 1 and 2 as diagnostics, not scores
Mock 1 · 29 NovMock 2 · 13 Dec
In the book: 1,120 questions with solutions
Phase 3Weeks 14–19 · 14 Dec – 24 JanAll ten mock tests
  • Mocks 3 to 10 in order, at the real exam clock time
  • Full 180 minutes, official negative marking
  • Next day: a written review of every wrong, skipped and slow question
3 · 20 Dec4 · 27 Dec5 · 3 Jan6 · 10 Jan7 · 13 Jan8 · 17 Jan9 · 20 Jan10 · 24 Jan
In the book: 10 mock tests, keys and worked solutions
Phase 4Weeks 20–21 · 25 Jan – 6 FebFinal two weeks: nothing new
  • Last-minute sheet, read once a day
  • Do-not-skip checklist, ticked only from memory
  • Error log cut to one page; one timed re-attempt of your weakest mock
In the book: last-minute sheet, do-not-skip checklist

This is the plan from Section 14 of the book, which assumes about 35–40 study hours a week. Exam slot on 13–14 or 20–21 February? Repeat the final week.

What makes it different

Four confidence scores, not one number

Being sure that cache mapping will be examined is not the same as being sure about one particular cache question. Every question in the book separates those claims, and the last one is deliberately capped low.

QCOA.1 · Memory hierarchy → Cache mapping → tag directory size NAT · 2 marks
Topic 92%
Concept 83%
Question pattern 73%
Exact question 22%

Exact-question confidence never exceeds 35% anywhere in the book. Across 2000–2026 what GATE repeats is the concept and the computation, not the wording. Any higher number would be a lie told to sell a book.

Compiled from independent published paper analyses, cited in the book. Low weight is not low value: Digital Logic and Compiler Design are the most formula-stable subjects in the paper and give the best marks per hour of study. The book says which hours those are.

Syllabus alert

Computer Networks lost a third of its topic list for 2027

If you prepare from a 2026 book, you will spend days on protocols that are no longer in the syllabus, and under-prepare the ones that now absorb the entire Computer Networks allocation.

No longer in the 2027 syllabus
  • OSI / TCP-IP stack enumeration
  • ARP, DHCP, ICMP
  • UDP
  • SMTP, FTP, Email
  • Framing, Ethernet bridging
  • Shortest-path and flooding routing
Now carrying the full weight
  • TCP flow and congestion control
  • IPv4, fragmentation, CIDR, NAT
  • Distance-vector and link-state routing
  • Error detection, MAC, Ethernet
  • Switching and performance metrics
  • Socket API, DNS, HTTP

Digital Logic and Computer Organisation also changed. The tabular minimisation method and hardwired versus microprogrammed control unit design are now named explicitly, and those have almost no previous-year history to practise from. The book writes fresh questions for exactly those gaps.

A page from the book

Every question carries its evidence

QOS.1 · Operating System → System calls → fork() process counting · NAT, 1 mark

A process executes the following code. Assume every fork() succeeds and no process terminates early.

for (i = 0; i < 4; i++) fork();

The total number of child processes created is ______.

  • =15
Based on PYQs: GATE 2005, 2008, 2012, 2019, 2021, 2024 Last tested: 2024 Confidence: Topic 80 · Concept 72 · Pattern 64 · Exact 20

No question in the book is a reprint of a past paper. The years name where the concept was examined, so you can see at a glance whether something is live or dormant.

What this book will not claim

It will not tell you it knows the paper. GATE questions are set by committees and the year-to-year variation is real. Every prediction here is a ranking built from historical evidence, labelled as analysis rather than fact, with the reasoning shown so you can disagree with it.

It is an independent study aid. It is not published, endorsed or approved by IIT Madras, IISc or any GATE organising institute. Verify the official syllabus and dates yourself at gate2027.iitm.ac.in.

Questions people ask
Are these real previous-year questions?

No, and that is deliberate. Every question is newly written. Past papers are freely available and you should solve them too. What this book adds is the analysis of which concepts those papers keep returning to, and fresh questions built on exactly those patterns, so you are practising prediction rather than memory.

Is the 2027 syllabus really different?

Yes, in three sections. Computer Networks lost a large part of its topic list, Computer Organisation gained control-unit design and cache mapping as explicitly named items, and Digital Logic named the tabular minimisation method for the first time. The book shows the old and new wording side by side and re-weights everything accordingly.

Can you guarantee these questions will appear?

No. Nobody honestly can. The book gives you a ranked, reasoned view of what the evidence supports, with confidence figures that are explicitly analytical estimates rather than probabilities. Exact-question confidence is capped at 35% throughout for that reason.

I have only two months left. Is it still useful?

Yes. There is a short-path route built in: the Top 100 concept list, the do-not-skip checklist, the Tier 1 and Tier 2 questions only, and four of the ten mocks. That plan is written out in the revision section.

How do I get updates?

Updates are sent to the email address you buy with, until the February 2027 exam. If a correction is found, everyone gets the corrected edition.
