Instrumentation Engineering is one of the 25 papers of the GATE 2020 for which huge number of candidates appear ever year. IIT Delhi releases the GATE Syllabus for Instrumentation Engineering 2020 this year and organizes the exam. Applicants of this paper will have to go through the syllabus before starting their preparation for the test to have complete overview of the topics from which questions will be asked. Read the complete post to know more.

GATE Instrumentation Exam Pattern 2020
GATE IN paper will have MCQs and NAT type of questions. Out of 65 questions of the paper, 10 questions will be from General Aptitude. There is a negative marking for the MCQs but no negative marking for NATs. So, examines can attempt all the NAT questions as there is no negative mark for this section. The duration of the exam is 3 hours and it is an online test. So, it is necessary for the candidates to practice the mock tests as many as possible so that candidates be confident and attempt the test well.
