GATE 2021 Syllabus for CSE (Computer Science Engineering)

Every year, GATE Syllabus remains almost the same as the previous one, but there is a rare chance that GATE Syllabus will be changed. Students who would write the GATE exam must refer the GATE CS and the IT syllabus defined by IIT Bombay to start with GATE Preparation as the questions are formulated in accordance with the official GATE syllabus.

Understanding GATE syllabus prior to starting GATE preparation will help candidates effectively plan the preparation strategy and score better marks. The GATE CS and IT exam paper consists of questions from aptitude and core subjects (CS and IT).
