Hi Sridhar,

All the streams of engineering are pretty much easier if you really have interest on that particular subject. It is basically based on your interest sridhar else you should choose the stream as per your interest rather choosing it by seeing it's difficulty level.

Automobile Engineering is growing very rapidly now a days.The present scope of automobile engineering is not as much good as the scope of Mechanical Engineering but it can be brighter in future.

Let me tell you Sridhar, that automobile engineering is basically a sub branch of mechanical engineering.

Mechanical Engineering deals with the construction, design and operations of the machines while automobile engineering only deals with the functioning and construction of automobiles.

Therefore i would suggest you to go for Mechanical engineering as the job opportunities for the mechanical engineers are much better as compared to the Automobile or electronics engineer.

Hope it helps..!!

Good Luck
