Past 12 Year Question Papers of GATE-IN Instrumentation Engg.

GATE Instrumentation Engineering (IN) Previous 12 Years Question papers with answers.

Graduate Aptitude Test in Engineering (GATE) is an examination conducted by the Indian Institute of Science (IISc), Bangalore along with seven Indian Institutes of Technology on behalf of MHRD and Government of India to test the understanding of the candidates in various undergraduate subjects related to Science. GATE Qualification is mandatory for seeking admission to ME, M. Arch and Doctoral programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies. The score of GATE Examination is valid for Three Years from the announcement of the results and they are accepted by more than 900+ institutes across India.

A collection of previous years GATE IN Question papers with answers are provided below to give a better understanding about GATE Instrumentation Engineering upcoming examination.

The key points about GATE IN exam are:

• The exam is conducted ONLINE and is a duration of 3 hours.
• Questions are divided into three sections: General Aptitude, Engineering Mathematics, and Subject-specific part.
• Number of questions – 65 totaling to 100 marks
• Question type: Multiple Choice Questions (MCQs) and Numerical Answer Type (NAT) Questions of 1 mark and 2-marks respectively.
• Marking scheme: MCQs carry negative marks, while NAT questions don’t attract negative marking.

Here is a brief on the topics covered for GATE 2020 Instrumentation Engineering examination.
