We all know that gate 2019 will ask two type of question one type of question are multiple objective type and other is numerical objective type, During the online exam, the candidate must select the right answer for the questions for MCQs, while for the numerical type of questions, the candidate has to enter the numerical answer by using the mouse on a virtual keyboard.
Gate 2019 Exam Pattern for Mechanical Engineering
GATE
2019 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.

GATE 2019 Marks of Each Topic:
The
gate 2019 total number of question will 65, have 100 marks. In this exams 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.
