Graduate Aptitude Test in Engineering (GATE) is an online 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 knowledge of the candidates in various undergraduate subjects related to Science. GATE Qualification is a mandatory requirement for seeking admission to Master’s programs in Engineering/ Architecture/ Technology or Doctoral programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies.

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

The question paper consists of 2 types of questions:

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. For 1-mark MCQ, 1/3 mark will be deducted for a wrong answer. Likewise, for 2-mark MCQ, 2/3 mark will be deducted for a wrong answer.

Numerical Answer Type (NAT) Questions -Each NAT question carry 1 or 2 marks and for these questions, the answer is a signed real number, which needs to be entered by the candidate using the virtual numeric keypad on the monitor (keyboard of the computer will be disabled). No choices will be shown for these types of questions. The answer can be a number such as 10 or -10 (an integer only). The answer may be in decimals as well.
