Gate Exam Pattern for Mechanical Engineering (ME)
GATE Syllabus for Mechanical Engineering paper ask two type of questions first will objective in nature and each question will have choice of four answers. And second will Numerical Answer Questions, that type of questions will be no choices available for these types of questions. The answer for these questions is a real number to be entered by using mouse and virtual keypad displayed on the monitor. No negative marking for these questions.
In this paper each question (Both objective and Numerical Answer Questions) carries 1- or 2-marks questions in all the sections.
Duration & Timing Exam: 3 hours (180 minutes) hours duration.
 Questions Type No of Questions Maximum Marks General Aptitude+ Technical + Engineering Mathematics 65 100 Total 65 100
GATE 2019 Marks of Each Topic:
According to gate syllabus Mechanical pdf total number of questions will 65, have 100 marks. In this exam 10 questions will be from General Aptitude carrying 15 marks. Papers with the codes AE, AG, BT, CE, CH, CS, EC, EE, IN, ME, MN, MT, PE, PI, TF and XE, will include a compulsory Engineering Mathematics section carrying around 15% of the total marks, and General Aptitude section carrying 15% of total marks. The remaining 70% is reserved for the subject of the paper.
Negative Marking: in gate 2019 the negative marking scheme for 1-mark MCQs, 1/3 mark will be deducted for every incorrect attempt. In case of 2-mark MCQs, the candidate will be penalised 2/3 mark for wrong attempt for questions that aren’t attempted, zero marks will be awarded. There is no negative marking for numerical answer type (NAT) questions.
