Why GATE Preparation
lGATE is mandatory for pursuing M.Tech, MS in prestigious institutes viz.IISc Bangalore,IITs, NITs and other universities where good campus placements are available with attractive salary packages range from Rs.6 Lakhs to 30 lakhs per annum.
lGATE Coaching helps you to get in-depth knowledge in core subjects like Communications, Microwave, Electro Magnetic theory, Satellites, Signals & Systems, Controls which are very crucial for campus placements.
lOne may not attend for B.Tech tuitions for individual subjects at all if GATE coaching is taken. Which will definitely improve percentage. We are providing best faculty from Hyderabad & Delhi.
lSome of the prestigious organizations like BARC, Mumbai call for interviews for scientist jobs, based on GATE score/percentiles. According to Economic Times, around 70 PSUs(like BHEL, IOCL, NTPC …) are recruiting through GATE 2012. It will obviously be increased for GATE 2013. Those who get good GATE scores, are generally selected.
lIf you have good rank in GATE, you can try for admission in M.B.A in IISc, Bangalore, NITIE, Mumbai, one of the best institutes for management courses after IIMs.
lYou will get an UGC scholarship of Rs.8000/- per month if you are qualified in GATE and studying M Tech in any college, based on GATE score.
lIf you don't have first class in engineering, it will be a hurdle to apply for some of the jobs where minimum 1st class is required. You can overcome this obstacle by doing M.Tech in a premier institute by securing a good GATE rank.
lIf you desire to excel in research and development, it is advisable to join M.Tech/MS in IISc Bangalore or IITs and continue for Ph.D.
