GATE 2018 ME Review & Exam Analysis:
GATE exam is conducted every year as a gateway to postgraduate courses at the Masters and Doctoral level across the country. The score is also used by some Public and Private Sector Undertakings for employment processes. Direct recruitment to Group A level posts i.e., Senior Field Office (SFO Tele), Senior Research Officer (SRO) (Crypto) and SRO(S&T) in Cabinet Secretariat is now being done on the basis of GATE scores. It primarily tests the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/Technology/Architecture and post-graduate level subjects in Science.
The Indian Institute of Science (IISc) and seven Indian Institutes of Technology (IITs at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) jointly administer the conduct of GATE. The operations related to GATE in each of the 8 zones are managed by a zonal GATE Office at the IITs or IISc. The Organizing Institute (OI) is responsible for the end-to-end process and coordination amongst the administering Institutes. The Organizing Institute for GATE 2018 is Indian Institute of Science. This year it has released the notification and the candidates who had appeared for the GATE Mechanical exam can check Review & Section wise analysis here.

Exam Pattern:
The GATE 2018 consists of 65 questions for 100 marks. The exam paper consists of General Aptitude, Engineering Mathematics & Mechanical Engineering section. The duration of the exam is 3 hours. There will be both Numerical Answer Type (NAT) Questions & Multiple Choice Questions (MCQ). For 1-mark MCQs, 1/3 mark will be deducted for every incorrect attempt and 2-mark MCQs, the candidate will be penalized 2/3 mark for the wrong attempt. Also, questions that aren’t attempted, zero marks will be awarded and there will be no negative marking for numerical answer type (NAT) questions.
The paper includes General Aptitude (GA) section comprising 10 questions. 5 of these questions will carry 1-mark each, while the remaining 5 will each carry 2 marks, for a total of 15 marks.
