## GATE Syllabus for CSE – Computer Science and Information Technology.

Given here is the detailed **syllabus for GATE **Exam CSE Paper. The syllabus for Computer science and information technology has been published by IITs and IISC for the **GATE syllabus**. Mainly there are two components – Engineering mathematics, and CS-IT. Candidates who will be appearing in GATE must know the complete GATE exam syllabus before starting their preparation. The GATE CSE paper would contain 25 questions carrying 1-mark each (sub-total 25 marks) and 30 questions carrying 2-marks each (sub-total 60 marks). The question paper will consist of questions of multiple choice and numerical answer type. For numerical answer questions, choices will not be given. Candidates have to enter the answer (which will be a real number, signed or unsigned, e.g., 25.06, -25.06, 25, -25 etc.). The paper will also have 15 marks for questions on General Aptitude.

Please note – The GATE exam will also have General Aptitude section. The **General Aptitude section GATE syllabus** is defined separately.

Given below is the **GATE Syllabus CSE**.

**Engineering Mathematics**

**Discrete Mathematics**: Propositional and first order logic. Sets, relations, functions, partial orders and lattices. Groups. Graphs: connectivity, matching, coloring. Combinatorics: counting, recurrence relations, generating functions.

**Linear Algebra:** Matrices, determinants, system of linear equations, eigenvalues and eigenvectors, LU decomposition.

**Calculus:** Limits, continuity and differentiability. Maxima and minima. Mean value theorem. Integration.

**Probability:** Random variables. Uniform, normal, exponential, poisson and binomial distributions. Mean, median, mode and standard deviation. Conditional probability and Bayes theorem.
