GATE CS Notes (According to GATE 2025 Syllabus)

GATE stands for Graduate Aptitude Test in Engineering. GATE is a national-level exam conducted by IISc-Bangalore and the seven old IITs; GATE 2025 is going to be conducted by IIT Roorkee. GATE 2025 Notification has not been released yet. Official Notification of GATE 2025 is going to be released by IIT Roorkee soon. After clearing the GATE exam, candidates are eligible for Master of Technology (M.Tech)/Master of Engineering (ME) from the most prestigious institutes, and job opportunities in PSUs (Public Sector Undertakings). It is a computer-based online exam and the main goal of GATE CSE is to test the technical aptitude of engineers.

The GATE Computer Science exam is generally conducted in the first or second week of February, and the GATE score is valid for 3 years. The official notification of GATE 2025 Exam is yet not released. Stay tuned to our website for all the information regarding GATE 2025 Exam. The GATE exam is conducted once a year. The GATE exam consists of 65 questions, including 10 General Aptitude and 55 core subject questions. The duration of the exam is 3 hours.

There are three types of questions that come into the GATE exam:

Multiple Choice Questions (MCQs)
Multiple Select Questions (MSQs)
Numerical Answer Type (NAT)
