Mechanical Engineering

For placement-mechanical:
There are a very few job vacancies in mechatronics for freshers in very few organisations. Since you will not study some core subjects of mechanical engineering, you won't be able to clear GATE or any other exam. It might be a problem a problem if your goal is to do job.
For knowledge and projects- mechatronics:
It's obviously better in many ways. Thing is that you will neither be as good as a mechanical engineer nor as good as an electronics engineer so all you would be able to do is make projects and learn about both fields simultaneously. But the projects you will be able to do are better than projects in core branches.

Hi,
After your Diploma you can go for B.Tech Lateral Entry in any of the streams. It will be of 3 years rather than normal B.Tech, which is of 4 years. It means you can straight way enroll into 2nd year of your Bachelor's degree. Students prefer this course with an idea of securing a well-paid job after the completion of their professional degree course. So you can select any branch of engineering depending upon your interest among CSE, mechanical, electrical, civil, aerospace, biotechnology, food technology, biomedical engineering, information technology, chemical engineering, automobile engineering, electronics and computer engineering or any other.
Therefore, I would like to mention that there are few known private institutions like:
Lovely Professional University- Jalandhar, Institute of Management and Technology-Faridabad, Institute of Engineering and Management- Kolkata
These are the universities that offers top class learning environment to the students with extensive placement opportunities. These universities also offer various skill development programs, professional enhancement training and outstanding exposure to its students.
