Graduate Aptitude Test in Engineering (GATE) is a national level entrance examination conducted for admissions to Post Graduation programs like M. Tech, M.Arch, ME, PH.D. etc. It is held by IISc and seven IITs on behalf of NCB –GATE and MHRD. The examination will be conducted usually in the month of Feb/ March every year across many cities of India. The scores of the examination are accepted by more than 900+ institutes across India and is valid for three years after the announcement of results.
Know more about GATE EC Exam:
- This examination is conducted Online and is a duration of 3-hours.
- The Question Paper has a total of 65 Questions 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 – Multiple Choice Questions (MCQ) and Numerical Answer Type (NAT) Questions.
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: There will be negative marking for a wrongly selected answer.
Each NAT question carry 1 or 2 marks and no choices are given. 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). There is no negative marking for a wrong answer in NAT questions.
