GATE PI Old Question papers and keys

Graduate Aptitude Test in Engineering (GATE) is a national level entrance examination for admissions to Post Graduation programs like M. Tech, M. Arch, ME, PH.D. etc. conducted by IISc and seven IITs on behalf of NCB –GATE and MHRD to test the knowledge of the students in the stream of Science.

The scores of the examination are accepted by more than 900+ institutes across India and it is valid for three years post announcement of results.

GATE 2020 PI Exam details and Question Paper Pattern:

The GATE 2020 will be  a 3-hour duration examination which will be  conducted online. The question paper has 65 questions of 1 mark and 2 mark totalling to 100 marks. The question paper is divided into three sections: General Aptitude, Engineering Mathematics, Subject-specific section.

The exam contains two types of questions:

(i) Multiple Choice Questions (MCQ)

Each MCQ would carry 1 or 2 marks and a choice of four answers are given, out of which the candidate must choose the correct answer. Note that there will be negative marking for a wrongly selected answer.

(ii) Numerical Answer Type (NAT) Questions

Each NAT question carry 1 or 2 marks and no choices are given. There is no negative marking for a wrong answer in NAT questions.

The syllabus and a collection of previous years GATE PI Question papers along with answers are provided in PDF format which can be downloaded to get a better understanding about GATE PI examination.
