__ 10 Points to know about GATE__

1. 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, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India

2. Students in final year of Engineering or Passed out can apply for GATE. GATE is a MANDATORY for seeking admission with scholarship to Master’s program or Phd program in India.

3. GATE score for employment:- Most PSUs (IOCL, ONGC,BHEL, SAIL, BPCL, HPCL, NTPC, POWERGRID, EIL, NHPC, etc) have used GATE score to shortlist the candidates for recruitment and in future many Government Organization will use GATE score to shortlist candidate.

4. GATE Exam is conducted every year by any one of the IIT or IISc in the month of February, application forms are available in month of September AND GATE Result is announced in mid of March

5. The Paper of GATE is of 100 marks and duration of exam is 3 hours with 65 question out of which 35 question are of two marks and 30 question of one mark each with negative marking of 1/3 marks.

6. GATE score is valid for three year from the date of announcement of the result

7. GATE exam is conducted in almost all major cities of INDIA AND in COLOMBO (SRILANKA), DHAKA (BANGLADESH), DUBAI (UAE), KATHMANDU (NEPAL) & SINGAPORE

8. GATE is completely online exam AND virtual calculator is provided for calculation.

9. Scribble pads are provided to students in the examination hall for rough work.

10. GATE 2020 will be conducted by IIT Delhi.
