Please be very clear about your career goals. All you need to do is to first be clear: are you ready to study full time for the IIT entrance examination, and this is option number one. The second option is to enroll for a degree course and then also take up the IIT examination.
Please do note, the Information Technology (IT) industry is not expanding at the same level, as it was some ten years ago. Salaries have stagnated and there are instances where it takes eighteen months for the companies to give the formal appointment order to candidates selected through the campuses.
You see, like what they say in the IPL competition, it is always going to be Best Vs the Best, in terms of competing with the best, in your chosen field of specialization.
And where do you find the gateways to get there. Please do not get it wrong. These are the IIMs and the NITs, ONLY.
There is absolutely no choice. For instance, there is this fabulous institution called the National Institute of Technology (NIT) , Tiruchirapalli, where the Mechanical Engineering specialization is just too good. Literally, sixty per cent go on to reserve their seats on airplanes to the USA, every year, to do further studies, absolutely on merit!!
It is only in such institutions that you should study. For example, if you get an admission into IIT, Madras, or Kanpur or Kharagpur or Delhi, and or NIT, Tiruchirapalli. You see, when you study in the best of the colleges, and in Mechanical Engineering for example, you will rub shoulders with the best of peers in the same field and most of them will be from elite schools. They would have gone through the hard grind and you will also learn very fast.
Mechanical or Engineering disciplines will always have huge demand. They will always offer you very good jobs and you can confidently take on the world. Robotics, for example, will help you stay ahead and hence you should do a post graduate course in this field in some good University in the USA.
Alternatively, you can also apply to the three best Deemed Universities in India, where the highest standards of Engineering prevail. These deemed Universities are the VIT, SRM and the SASTRA Universities. Each of these universities also have very good placement records.
Please do note a BTech course from any of the top engineering colleges is your best investment for a very bright future.
