What is GATE?

The Graduate Aptitude Test in Engineering (GATE) is a national-level examination that evaluates candidates’ knowledge in engineering, technology, and science subjects. It serves as a gateway for admission to postgraduate and doctoral programs in reputed institutions and is also considered for financial assistance through scholarships and fellowships. Additionally, several Public Sector Undertakings (PSUs) use GATE scores for recruitment, making it a crucial exam for those seeking careers in government organizations. Conducted as a computer-based test, GATE assesses conceptual understanding, problem-solving skills, and analytical abilities through multiple-choice and numerical answer-type questions. The exam is open to graduates and final-year students from recognized institutions, providing them with opportunities for higher education, research, and professional growth.

GATE 2025

IIT Roorkee is responsible for conducting GATE 2025, a national-level exam designed to assess candidates’ knowledge in undergraduate engineering, technology, and architecture subjects, along with postgraduate science disciplines.

The exam will take place over two weekends in February 2025 (on Saturdays and Sundays) and will be entirely computer-based. A total of 30 subjects, also known as “papers,” will be covered. Test centers are located across various cities in India as well as in six international locations.

Candidates have the option to appear in either one or two papers. The GATE score is a measure of a candidate’s performance relative to others and is calculated using past exam data. This score remains valid for three years from the date of the result announcement.

Eligibility

Candidates with a bachelor’s degree in Engineering, Technology, Architecture, or a master’s degree in Science are eligible to apply.

GATE Score Validity

The GATE 2025 score is valid for three years from the date of the result announcement. It is used for admissions to postgraduate programs and recruitment in Public Sector Undertakings (PSUs).

Application Process

Interested candidates must apply online through the official GATE 2025 website. The process includes registration, filling personal and academic details, uploading documents, and paying the application fee.

Exam Pattern

The GATE 2025 exam consists of Multiple Choice Questions (MCQs), Multiple Select Questions (MSQs), and Numerical Answer Type (NAT) questions. The exam duration is 3 hours, with a total score of 100.

Scholarship/Assistantship for Postgraduate Programs

To avail of financial assistance, candidates must secure admission in government-supported institutions. Selection may be based on GATE scores alone or a combination of GATE scores, interviews, and academic records.

GATE for Employment

Many PSUs use GATE scores for recruitment, including:

Indian Oil Corporation Limited (IOCL)
Power Grid Corporation of India (Power Grid)
National Thermal Power Corporation (NTPC)
