The GATE exam for Computer Science and Engineering (CSE) is a national-level test for postgraduate admissions to IITs, NITs, and PSU recruitment. It evaluates candidates on their comprehensive understanding of core computer science subjects across 12 key topics, serving as a critical step for pursuing M.Tech, PhD, and careers in top tech organisations. ExamPrev covers 1000+ GATE CS previous year questions from 2008 to 2026 — organised subjectwise and yearwise with detailed solutions.
Algorithms & Data Structures
Master sorting, searching, graph algorithms, dynamic programming, and complexity analysis. GATE consistently tests time and space complexity, greedy strategies, and divide-and-conquer — making this one of the highest-weightage topics.
Practice Algorithms Questions →Computer Networks
Deep-dive into OSI and TCP/IP models, routing protocols, IP addressing, subnetting, transport-layer protocols, and application-layer services. One of the highest-weightage subjects in GATE CS with 8–10 marks every year.
Practice Networks Questions →Operating Systems
Covers process scheduling, memory management (paging, segmentation), deadlock detection and prevention, file systems, and I/O management. GATE frequently tests CPU scheduling algorithms and virtual memory concepts.
Practice OS Questions →DBMS
Understand relational algebra, SQL queries, normalisation (1NF–BCNF), ER diagrams, transaction management, ACID properties, and indexing. GATE tests both conceptual understanding and hands-on SQL problem-solving skills.
