Graduate Aptitude Test in Engineering (GATE) is a national level entrance examination for admissions to Post Graduation programs like M.Tech, M.Arch, ME, etc. conducted by IISc and seven IITs on behalf of NCB –GATE and MHRD.
The scores of the examination are accepted by more than 900+ institutes across India and is valid for three years post announcement of results.
GATE 2020 BT Exam details and Question Paper Pattern:
The GATE 2020 will be a 3-hour duration examination which is conducted online. The question paper has 65 questions of 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. 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.
The syllabus and a collection of previous year GATE BT Question papers along with answers are provided in PDF Format to help you download so as to give a better understanding about GATE BT examination.
