GATE questions, solved.
And where they're used.
Previous-year questions from official GATE papers, with step-by-step solutions checked against the official answer keys, and a note on where each concept shows up in real engineering work.
77 questions · 3 subjects · 5 official papers · 37 numerical (NAT), 34 MCQ, 6 MSQ · Updated 15 Nov 2026
Mechanical so far: Fluid Mechanics, Strength of Materials, Thermodynamics. More subjects are being added. Questions from GATE 2022 (IIT Kharagpur), 2024 (IISc Bengaluru), 2025 (IIT Roorkee) and 2026 (IIT Guwahati). For dates and syllabus see GATE 2027 Mechanical.
How are these GATE solutions checked?
Every question is copied from the official GATE paper published by that year's organising institute. Skill-Lync engineers work each solution independently, and a script recomputes every numerical answer and checks it falls inside the official answer-key range. Any answer that doesn't match the key is dropped, not published.
What is a NAT question in GATE?
NAT means Numerical Answer Type. There are no options: you type a number, and it is marked correct if it falls inside the range given in the official key, for example 404 to 414. NAT and MSQ questions carry no negative marking; wrong MCQ answers lose 1/3 of the marks.
Are previous-year GATE questions enough to prepare?
They show what is asked and how deep, but they are not enough on their own. Use them after you finish a subject: solve a topic's questions on time, check the method, not just the answer, and go back to theory where you got stuck. Then attempt full papers under exam conditions.
Do I need GATE for a core mechanical job?
Not always. Many PSUs recruit mechanical graduates through GATE scores, and GATE is the route to an M.Tech at IITs and NITs. Private core employers (automotive, CAE and CFD services, design firms) usually hire on skills, projects and interviews and don't ask for a GATE score.
