Why GATE examination ?
- To get admission in the highly reputed institutes like IISc, IIT's, NIT's etc
- It gives more knowledge, which makes the person independent in life.
- It helps to get good job and the job satisfaction.
- In many private institutions, GATE is the mandatory qualification for admission to postgraduate programs.
- In many Government organization,the GATE qualification is the
important criterion for applying to post of an Engineers/Scientist.
- Some of the Universities from abroad also considers the GATE score for admission to their Master programs.
- Indian Institute of Managements consider the GATE score for their
postgraduates programs. For more details, please see the respective IIMs
sites.
