Computer Science and Engineering

Ravi, there is always a trend which gets established in the job market / scenario and this trend sustains for some time and then changes again. As of now the inclination is more towards Computer Science.

Well pursuing any course from an approved University from UGC is always good. However,the final call is yours.

You can go for any job in IT department in government sector or PSU. It will be great if you crack GATE exam because it will help you in getting good job in IT companies like CRIS CRWC n lots more

Don't worry.Actually your state rank is not so good, so you have to wait for 3rd round.After that 4th round is also there.but dont worry u will definitely get a college according to your need.

If you have not learned even after 4 years of engineering, it will difficult for you to learn by doing few short term courses or self learning. Therefore, it is suggested that you change your stream. You may evaluate MBA to change your stream.
