Hey Kanukuntlasanjana

Both, Computer Science Engineering And Mechanical Are Good , But In My Opinion In Mechanical Stream Is Mostly Theortical. You Just Have To Mug Up Stuff And Vomit It In The Exams To Pass.No Practical Knowledge.If You Want To Be An Entrpreneur Or Join The Industry Right After Graduation , Take up CSE. If You Are In More Practical Approach That Computer Science Engineering Is Better That Mechanical Engineering Which Is Basically Theortical.

I Hope It Helps 

Good Luck 

Hey, if you ask someone about the difficulty level of CSE or mechanical branch, then it will vary from person to person. As it only depends on an individual, his favourite fields and subjects. As if you like computer and coding then you should opt for CSE. And if you like physics and machines then you should opt for Mechanical branch. But we can say that CSE is slightly easier than mechanical.

it depends on your basic understanding of the subject. If you are good at physics, especially the class 11th part, Mechanical Engineering will be very easy for you. On the other hand, computer science lovers and coders find CSE easy to specialize in. So, find out what suits your interests and skills. But, on a large scale, it has been noticed that more students fail at CSE exams than mechanical across different colleges in India. CSE is a tough subject and its demand is therefore higher.
