Hey Preet,
Basically if a student has interest in anyone of them then it would be easy for him to pursue. If you have a fasciantion with physics and automobiles, mechanical would be easy for you to digest.
Hwoever, if your are fascinated with the IT field and have a logical mind to handle the coding background of C, Java IT would be easier for you.
It depends on each individual.
For some,mechanical is easy while for some IT is.
But if you force yourself to study something, it can become very difficult even to pass.
In the end, if you can mug up mechanical will be easier in some way. It is very difficult to mug up and score high. It is easier if you study and understand the basics and can use it to solve the problems.
Mechanical is like physics while IT is like mathematics.
Hope it helps,
Good luck!
