GATE XL ( Life Sciences ) - Lavkeshsharma - 09-08-2017
Graduate Aptitude Test in Engineering (GATE) is an examination conducted jointly by the Indian Institute of Science (IISc), Bangalore and the seven Indian Institutes of Technology (at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) on behalf of the National Coordination Board (NCB)-GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India.
Qualifying in GATE is a mandatory requirement for seeking admission and/or financial
assistance to: (i) Master’s programs and direct Doctoral programs in
Engineering/Technology/Architecture and (ii) Doctoral programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies. Even in
some colleges and institutions, which admit students without MHRD scholarship/assistantship, the GATE qualification is mandatory. Further, many Public Sector Undertakings (PSUs) have
been using the GATE score in their recruitment process.
Note that the GATE 2018 score is valid for THREE YEARS from the date of announcement of the results.
The following categories of candidates are eligible to appear in GATE:
Bachelor degree holders in Engineering/ Technology/ Architecture (4 years after 10+2) and those who are in the final or already completed.
Master degree holders in any branch of Science/ Mathematics/ Statistics/ Computer Applications or equivalent and those who are in the final or pre-final year of such programmes.
Candidates in the second or higher year of the Four-year Integrated Master degree programme (Post-B.Sc.) in Engineering/ Technology
OR in the third or higher year of Five-year Integrated Master degree programme and Dual Degree programme in Engineering/ Technology.
3. Examination structure :
The GATE examination consists of a single paper of 3 hours duration, which contains 65 questions carrying a maximum of 100 marks. The question paper will consist of only multiple choice objective questions. Each question will have four choices for the answer. The candidates will have to mark the correct choice on an Optical Response Sheet (ORS) by darkening the appropriate bubble against each question. There will be negative marking for each wrong answer, as explained in Question Paper Pattern.
