# Previous 12 Year Papers and Keys of GATE-MN

### GATE Mining Engineering (MN) Previous Question papers with answers Graduate Aptitude Test in Engineering (GATE) is an examination held in February by both the Indian Institute of Science (IISc), Bangalore and seven Indian Institutes of Technology on behalf of MHRD and Government of India to test the knowledge of the candidates in various undergraduate subjects related to Science. GATE Qualification is mandatory for the students seeking admission to Master’s programs like ME, M. Arch and PH.D. programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies.

### GATE Exam Pattern

The GATE Exam is for a duration of 3 hours and the pattern of the Question Paper is same as the other branches of GATE examination. The Question paper has 65 questions of 1 mark and 2-mark each totaling to 100 marks for the entire paper. The pattern of the Question Paper is same as the other branches of GATE examination.

The question paper consists of 2 types of questions:
Multiple Choice Questions (MCQ) and

• Multiple Choice Questions (MCQ) – Each MCQ would carry 1 or 2 marks and they are objective in nature, and each will have a choice of four answers, out of which the candidate must choose the correct answer. Note that there will be negative marking for a wrongly selected answer.
• Numerical Answer Type (NAT) Questions -Each NAT question carry 1 or 2 marks and for these questions, the answer is a real number and no choices are provided. There is no negative marking for a wrong answer in NAT questions.

The score gained for GATE Examination is accepted in more than 900+ institutes across India and is valid for three years post results.
