GATE 2021 :
GATE 2021 Exam - Indian Institute of Technology (IIT) Bombay will lead the GATE 2021 test on February 5 to 7 and 12 to 14. Graduate Aptitude Test in Engineering, normally known as GATE 2021 test, will likewise have two new subjects - Humanities and Social Science (XH) and Environmental Science and Engineering (ES). Additionally, because of winning Covid-19 circumstances, GATE 2021 qualification standards have likewise been loose. Up-and-comers who are in the third year will likewise be qualified for showing up in GATE 2021. Entryway 2021 enlistment was open from September 11 to October 7 (without late charge) and till October 14 (with the late expense) in online mode.
IIT Bombay has likewise presented another kind of inquiry - Multiple Select Questions (MCQs) in GATE 2021. Likewise, up-and-comers can show up in more than one GATE paper. The schedule for all the papers of GATE has been reexamined. Entryway 2021 will be directed as a Computer-based test. Up-and-comers will have the option to utilize the GATE scores for M.Tech confirmations or PSU enrollments. The scorecard of GATE 2021 will be legitimate just for 3 Years.
Requirements for GATE Application:
- Age Limit - There is no age limit for the GATE 2021 exam.
- Nationality - Should have Indian nationality. However, if candidates of other nationalities will also be able to apply for GATE 2021 if they meet the eligibility.
- Qualification - Should have passed or currently be in their pre-final/final year of Bachelor’s Degree in Engineering/Technology (B.E./B.Tech) or Postgraduate (M.Sc) degree in any relevant science subject. For the details, read GATE Eligibility Criteria 2021.
- Required Percentage - Candidates do not require to have any minimum pass percentage in the qualifying exam.
