# GATE Syllabus 2022 for CSE and IT and latest gate syllabus updated. The syllabus is very important to crack any competitive exam. Without knowing the syllabus we can not prepare well for any exam. If we want to prepare for any exam, first we need briefly examine a particular subject syllabus and paper pattern.

## Latest Gate CSE and IT (Revised) syllabus new updated

### Section 2: Engineering Mathematics.

According to the gate computer science council, the engineering mathematics section is the same as all engineering branches but follows the mathematics syllabus for mainly computer science branch students.

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.
