GATE

Hello,
Thanks for Asking.
Yes, after qualifying GATE exam, you can enter into the teaching field.
The benefits of qualifying Gate Exam:
* Pursue M.Tech or M.Sc from India or abroad.
* If your GATE score is low but you want to do M.Tech or MS from a reputed institute, you can work as an assistant to the professor for a year or two. This way you can get a really useful recommendation (LOR) necessary for pursuing higher studies abroad.
* If your score is high, get into an IIM (Indian Institute of Management) B-school through GATE Score
* You can teach at GATE coaching classes (Part-time or Full-time).
* Go for recruitment in PSUs such as BHEL, IOC, NTPC, BPCL, BARC, HPCL, etc.
