# GATE CS 2022 Syllabus

In previous GATE authority has revised syllabus of GATE CS and has added few sections as you can see/analyse here.

In this year, GATE authority did not make any change in syllabus of GATE CS 2022. It is same as syllabus of GATE CS 2021.

IIT Kharagpur is organizing GATE 2022. There are two part of GATE CS 2022 syllabus (same as GATE CS 2021) :

- General Aptitude (GA) – for 15 marks
- Computer Science and Information Technology (CS/IT) – for 85 marks

These topics will be covered in these two parts :

### 1. General Aptitude (GA) – for 15 marks

**Verbal Aptitude Basic English grammar :**

tenses, articles, adjectives, prepositions, conjunctions, verb-noun agreement, and other parts of speech Basic vocabulary: words, idioms, and phrases in context Reading and comprehension Narrative sequencing

**Quantitative Aptitude Data interpretation :**

data graphs (bar graphs, pie charts, and other graphs representing data), 2- and 3-dimensional plots, maps, and tables Numerical computation and estimation: ratios, percentages, powers, exponents and logarithms, permutations and combinations, and series Mensuration and geometry Elementary statistics and probability

**Analytical Aptitude Logic :**

deduction and induction, Analogy, Numerical relations and reasoning
