Hi Anandh,

There is no specific measure to say which is tougher between mechanical engineering and electrical engineering it totally depends on you .

If you are interested in subjects or topics related to electrical engineering like current electricity chapter of 12th standard  then electrical engineering will be easier for you and if you are interested in mechanics then it will be easier for you.

I suggest you to take only that stream in which you have better understanding and interest otherwise if you take any other stream in which you are not interested then things will get tougher for you in future.

Hope this answer helps you.
