GATE CSE 2027 · Top 10 Chapters The 10 chapters GATE asks almost every year: every topic, full notes, cheat sheets and traps (181-page PDF)

80+ in GATE doesn't come from giving every chapter the same time. It comes from never losing the marks that come back every year.

We mapped 1,844 GATE CSE questions from 2008 to 2026 to their chapters and topics, and ranked every chapter by how often GATE asks it. Ten chapters stand out: each was asked in 10 to 12 of the last 13 papers, and together their questions are worth about 14 marks in an average paper.

📌 THE 10 CHAPTERS 01. Cache Organisation & Mapping (COA) 02. Paging, Page Tables & TLB (OS) 03. Minimum Spanning Trees (Algorithms) 04. Graph Traversals: BFS and DFS (Algorithms) 05. CPU Scheduling (OS) 06. Pointers and Arrays (Programming & DS) 07. Binary Search Trees (Programming & DS) 08. C Basics: Operators, Expressions & Control Flow (Programming & DS) 09.
