2. Do you want to know the functioning of your home electrical appliances ?

5.Do you like to make some new mechanism ?
6.Do you like to use your engineering skills for a common man life ?
if yes then you are at right place this is the branch for you. This branch require a real hard work. In most of the colleges mechanical and production are different branches but there syllabus content are more or less similar but in few college this is combine. There is a misconception that in this branch's job opportunity are less as compared to computer science and electronics. Again it's depend upon individual .This is called evergreen branch ,now a days there are a lot of job opportunity and money in this sector if you have talent and ready to work hard.
