Hello Ranjit!

That's a tough question. It completely depends on your inclination. Which subjects do you like the most? Is it biology or is it maths and physics?

Medical is a very noble profession. I would say, if you can actually save lives .. there's nothing more satisfying! But you'll have to work a lot harder.

If you're very much interested in Engineering, and do want to invent solutions to the people's daily life problems and not just wait to get placed in a 9-5 Job, you'll also have to work hard a lot.

Basically the two fields aren't comparable.

Only thing that you can compare is the courses. If by chance you cannot get into a government medical college, private medical colleges have insanely high fees! Which isn't that high in Engineering colleges. So you could consider that depending upon your financial condition.

Also it's a general assumption that you've to study for a lot longer in medical, but if you want to get your post graduation and then do phd you'll have to study for engineering too.

Hope this helps!

Best of luck :)
