Mechanical Engineering

Both are good streams but the demand of mechanical engineering is always more in the market.

The knowledge of programming languages may help you in designing the software part of mechanical devices you are manufacturing. You have the hardware knowledge and knowledge of softwares will help you designing the technology completely and it will help you in designing technologies related to mechatronics.

Dear Abhishek,

Dear Aman,
As you opted for Diploma in mechanical engineering. Now it is best for you to take LEET exam conducted by each state every year and get a good college and pursue B.Tech in mechanical engineering.

Hello Deepu,
There are lots of colleges and deemed universities in Chennai and Hyderabad. But, why stick to only these two cities? Of course, if this is your aim then so be it. However, general rule of probability will apply, meaning as you restrict choice, you have to work hard to get a better ranking as only better ranking can take you to your goal.
I am sending link for colleges in Chennai. Similar link you can find on Shiksha portal:

Mechanical engineering graduates after completion of B.Tech can undergo 1-year duration Graduate Marine Engineering (GME) course to enter into merchant navy as marine engineer. This course is offered by lot of institutes approved by the Directorate General of Shipping.

Maximum colleges take direct admission in the distance engineering course through your 12th or Diploma percentage. There are very few colleges that conduct entrance test:

Hi Pankaj,
You can pursue B.Tech in mechanical engineering through distance education or you can do AMIE course. In AMIE course, you will have to clear only 13 subjects. After clearing this, you will get a degree in mechanical engineering.

Hello Manthan,
Your GATE score of last appears way below your capabilities. So, something went wrong during exam? But, forget about that episode. You are now appearing afresh. Take into account your weak areas of last year and if you plug these I am sure this year you will get desired score.

Hi,
You can get into mechatronics as it is a good branch.
