GATE - GRADUATE APTITUDE TEST IN ENGINEERING

    One thing, i want to say about GATE . GATE exam is conducted by IIT's and Government of India. All engineering graduates and final year students are eligible to write the GATE exam. This GATE score will help us to place on the government companies like BHEL, BSNL, NTPC and HAL etc. And then high score will help to join in IIT's and more universities for continuing higher studies in India. This is very good opportunity for final year students. If you are interested in core papers, you will never fail in GATE.

DO WELL PREPARATION AND HARD WORK. ALL THE BEST!!!!!!!!!!!!!!!!!!!!
