GATE Previous Year Mechanical Engineering (ME) Paper Analysis

This year, the mechanical engineering paper was conducted in two sessions viz.

Session 1 (Forenoon): 9:30 am – 12:30 pm

As per the students, the General Aptitude section had easy and direct questions. On the technical side, the Math section had about 8 questions (4Qs were of 1 mark and 4Qs. were of 2 marks) and about 47 questions were from ME branch.

There were about 26 questions in NAT section. 10 questions were of 1 mark and 16 questions of 2 marks. They were a bit lengthy and evaluated the candidate’s concepts.

Tabulated below is the section-wise important topics asked in GATE ME paper:
