The document provides information about GATE (Graduate Aptitude Test in Engineering). GATE is an online exam for engineering students and tests concepts in engineering and science. It is used for admission to postgraduate programs at IITs, IISc and other colleges. A high GATE score also makes students eligible for research fellowships and jobs at PSUs. The document outlines the eligibility criteria, exam pattern, syllabus and previous year cut-offs for GATE. It also provides information about preparation for PSU exams, cut-offs of some PSUs and specializations offered in Mechanical Engineering.

2. What is GATE?
• GATE stands for Graduate Aptitude Test in Engineering.
• An online all India examination for students of undergraduate
subjects in Engineering/Technology/Architecture and post-graduate
level subjects in Science .
• Organised by Indian Institute of Science(IISc) and the 7 IITs.

3. Why GATE?

programs in IITs, IISc, NITs and other reputed colleges.
• Scope of research in various institutes under reputed faculty
members.
• Eligibility for the award of Junior Research Fellowship in CSIR
Laboratories.
• Most PSUs like ONGC, BHEL, etc use GATE score for their recruitment.
