The GATE is a national-level exam which is conducted in India that primarily tests the comprehensive understanding of various UG subjects in engineering and Science for admission into the M.E. /M.Tech. Ph.D. programme and Job in PSUs. However, the GATE exam is not conducted for JRF. The NTA has been entrusted by the UGC with the task of conducting UGC NET which is a test to determine the eligibility of Indian nationals for Assistant Professor and JRF and Assistant Professors in Indian colleges and universities. NET is a national-level test of the UGC for the award of a JRF to eligible students. PG students, who want to undertake research studies in the field of Engineering, Science, Humanities, Social-Sciences, or more can apply. I hope this will help you.

Electronics and Communication Engineering, Mining, Physics and Electrical are the toughest branches for the Graduate Aptitude Test in Engineering because of their competition.

IIT JAM and GATE Exam are national-level entrance exams for post-graduate programs at IITs, NITs, and IISc Bangalore. IIT JAM is a common entrance test for admissions in Masters courses such as M.Sc, Integrated Ph.D. , Joint M.Sc-PhD, and M.Sc-PhD Dual Degree whereas the GATE is a national-level exam that provides admissions to the master of technology programs such as ME, M.Tech, and Ph.D. courses. The IIT JAM Exam covers 7 subjects, whereas the GATE Exam covers 29. IIT-JAM Eligibility Criteria:
Bachelor's degree in Science (Physics, Chemistry, Biology, and Mathematics) for three years from a recognised university if you have appeared or are going to appear in the final year examination of a Bachelor's degree. There are no age limit criteria. Eligibility for GATE:
You should have a 4-year BE or B.Tech degree (after 10+2) or a 3-year Diploma in engineering, technology, architecture, commerce, or the arts. Candidates who have completed a 5-year degree programme in B.Arch. are also eligible for the Graduate Aptitude Test in Engineering Exam. The organizing IIT also allows other degrees, such as an integrated degree in B. S. , M. S. , M.Sc, M.Sc. , or M.Tech. IIT JAM Exam Pattern:
Section A: Total Number of Questions and Their Type; 30 MCQ. Marking scheme:
1/3 of marks will be deducted For 1 mark question.
2/3 marks will be deducted For 2 marks questions. Section B: Total Number of Questions and Their Type: 10 MCQ. There is no negative marking. Section C: Total Number of Questions and Their Type; 20 Numerical Answer Types (NAT). There is no negative marking. Total Questions: 60. Total Marks: 100
GATE Exam Pattern:
