I want become a mechanical engineer
Why though?
What exactly do you think that a mechanical engineer does?
Are there any aspects of Mechanical Engineering that interest you?
As per your dream to become a mechanical engineer you should complete your 12th first with scienceand then should give Engineering Entrance exams like jee ,wbjee ,bitsat etc or you can try in private colleges also. Then you have to choose mechanical branch during counseling.
Thus you will become a mechanical engineer.
One does not become a mechanical engineer just by choosing it as a branch in any college. After getting the said branch,, there are 4 years, 8 semesters full of gruelling practicals, projects, assignments, tutorials, vivas, mid sem exams and end sem exams. All these need to be cleared in the course of 4 years after which one gets the B Tech degree.
This part is very important for all those people who say that life after 12th is chill. It never was, never is and never will be.
The eligibility criteria is you need to pass class 12 with atleast 75%marks with Physics chemistry and Mathematics. Appearing candidates can also apply for the same.
Feel free to comment if you have any doubt
Good luck
