After studying Diploma in Mechanical Engineering if you want to go for further education then you have to go for BTech course. Now if you take admission in BTech after your diploma then you get a chance to change your stream as well as you will get admission directly to the 2nd year of BTech program through later entry. So this can be a option. Apart from this you can apply for government job examination such as RRB JE, SSC JE etc or you can also apply for vacancies in private industries as well.
