Engineering Scope

Hello,
After completing class 12th, you need to appear for various entrance examinations. I would suggest you to appear for JEE Mains and Advanced. These two entrance examinations provide admissions to IITs/ NITs and other government colleges, which are cost-effective.
I would also suggest you to appear for individual state examinations (OJEE in Odisha, EAMCET in Andhra Pradesh/ Telangana, COMEDK in Karnataka, etc.). These exams also guarantee you good colleges and serve as a backup in case things don't end up the way you've planned for IIT/ AIEEE.
Every state has its own share of good engineering colleges. So, don't underestimate or overlook them. They can prove to be vital. The more the entrance examinations you appear for, the more the options you will have for choosing colleges.
Certain private colleges like SRM, KIIT - Odisha, GITAM - Vishakhapatnam and ITER - Odisha conduct their own entrance examinations. You can opt for these as well.
After the results of those entrance examinations are announced, if you have a valid score and rank, you can attend the counselling procedure for the respective entrance examination. During the counselling procedure, you can select a college of your choice and the branch of engineering (automobile engineering in your case).
Kindly refer to the link below for colleges for automobile engineering:

Kindly filter the list based on location and other preferences.
I hope it helps. If so, kindly upvote this answer. If you've any further questions, kindly revert.

Hello Kiran,
M.Tech:
This is the course that most students pursue once they complete their engineering. This course has many takers because of the job opportunities that it has to offer. If you really want that edge over B Tech grads or you have set your eyes on becoming a lecturer, this course is highly recommended. The course is two years long and the demand for M Tech grads isnt going to die any soon.
M.Sc. or M.S.
Engineering graduates are eligible to pursue relevant Masters Degree in Science. M.Sc. or M.S. programs can be pursued by them. The key is to select a relevant and rewarding field of specialization. It will also help one take a step towards a rewarding career in the R&D sector!
Branch specific Skills Oriented courses
There exist many technical and skill based courses, which engineering graduates may pursue. Such courses are branch-specific in nature. For example, wiring engineering will suit mechanical and electrical engineering graduates. Similarly, piping engineering will suit civil and mechanical engineering graduates. Such courses are job oriented and will certainly add to the skill set of engineering graduates. Apart from that, such courses are short term in nature.
MBA:
Many companies are looking for engineers with great management skills. If you get an MBA after your B Tech, your value rises exponentially. There is no need to hurry and enroll for an MBA soon after B Tech. You may take up a job, prepare for MBA entrance at the same time and enroll after a couple of years. In this way you have three advantages: you have B Tech degree, work experience and an MBA degree by the time you finish Management course.
PGDM:
For those who are not interested in MBA, PGDM course will come handy. It is a PG Diploma course related to management studies. One may opt for general management studies or may even choose a specialization! PGDM programs are generally around 1-2 years.
Various Software Courses:
This will be helpful to Computer engineering and IT engineering students. The key is to stay up-to-date. There are various private institutes offering software and hardware courses.
Apart from the above mentioned courses, you may even prepare for competitive exams like GATE, UPSC as well as State-wise PSC exams. Many well known PSUs are recruiting GET (Engineering Trainees) through GATE score. A good score in the exam will help you land a good Government job! State-wise PSCs can be used to obtain state Government jobs.
