GATE CSE Exam Pattern 2022 consists of 65 questions of 100 marks in total. The questions asked will be one of the three types - Multiple Choice Questions (MCQ), Multiple Select Questions (MSQ) and Numerical Answer type Question (NAT). About 72% weightage (of the total marks) is given to GATE CSE Core syllabus, 15% to General Aptitude and 13% to the Engineering mathematics.The important topics from which the questions are asked are - Digital Logic, Algorithms, Theory of Computation, Computer Organizations etc.Candidates appearing for the GATE CSE paper can also choose to appear for Mathematics (MA) as their second paper.

GATE CSE Previous Year Paper Analysis

The data presented above regarding the weightage of sections has been compiled by the detailed Paper Analysis of the Previous years question papers. However the data from each year's question paper also has other uses than estimating the ‘general average weightage of sections’, it can also show us the trends of weightage from different sections over the years. SO for that purpose a brief analysis of the previous year question papers are given below

Sample Questions from Major Topics

GATE CSE Exam Pattern 2022: Sample Questions from Major Topics

Given below are the 1 & 2 Mark Questions from GATE CS Previous Years Papers With Solution

  • Ques. What is the worst-case time complexity of inserting n2 elements into an AVL-tree with n elements initially?

Answer. Θ(n2 log n)

Explanation: Since the AVL tree is a balanced tree, the height is O(log n). So, time complexity to insert an element in an AVL tree is O(log n) in the worst case.

  • Ques. A processor has 64 registers and uses a 16-bit instruction format. It has two types of instructions: I-type and R-type. Each I-type instruction contains an opcode, a registered name, and a 4-bit immediate value. Each R-type instruction contains an opcode and two register names. If there are 8 distinct I-type opcodes, then the maximum number of distinct R-type opcodes is _______.

Answer: 14 (Note – This question was Numerical Type.)

  • Ques. Consider a database implemented using a B+ tree for file indexing and installed on a disk drive with a block size of 4 KB. The size of the search key is 12 bytes and the size of the tree/disk pointer is 8 bytes. Assume that the database has one million records. Also, assume that no node of the B+ tree and no records are present initially in the main memory. Consider that each record fits into one disk block. The minimum number of disk accesses required to retrieve any record in the database is ___________?

Answer: 4 (Note – This question was Numerical Type)

  • Ques. Raman is confident of speaking English _______ six months as he has been practicing regularly _______ the last three weeks.
