Exam Pattern for GATE 2019 Instrumentation Engineering (IN)

The most important and prior step is to go through the exam pattern for the same. The exam pattern is officially given by the GATE conducting authority. So it is recommended to go through it thoroughly and then plan the study schedule according to the weightage of different topics.

The paper pattern is as follows-

  TOPICS MARKS DISTRIBUTION
Technical Section 70 marks
General Aptitude 10 Questions of 15 marks
Engineering Mathematics 15 marks
Total Marks 100 marks
Total Questions 65 questions
Time Duration 3 hours

It consists of basically two type of questions namely

  1. Multiple Choice Questions which are objective type questions each having 4 choices of answers. They are of 1 or 2 marks in all Sections. It also includes negative marking. Hence, for each correct answer 1 will be added and for each incorrect answer 0.33 mark will be deducted and for each 2 marker question correct answer gives 2 marks and incorrect answer deducts 0.66 marks.
  2. Numeric Answer Questions are different from Previous MCQs. They don’t include any choices they have answers which are real numbers which are to inserted by virtual keypad appeared on the monitor via mouse. They also carry 1 or 2 marks in different sections. No negative marking is there for the same.
