Hi,

Mechanical engineers work mostly in engineering services, research and development, and manufacturing. EdX offers online mechanical engineering courses for free from top engineering schools.

There are no such constraints in Distance b tech which makes it best as you gain a degree along with the skill and knowledge of b tech while you work. There is no such eligibility for your work experience or you have to give an entrance exam to enroll b tech in Distance.

Hope this helps

Wish you luck
