Automobile Design

Why not. You can do car designing after completing your XII exam. As my cousin's brother also completed his Bachelor's degree in Automobile and transportation design so I know it very well. He was selected UID for his study so I can share their admission process with you. After completing your higher secondary exam from any recognised board with minimal 50%, you have to sit for their admission test. There will be 3 rounds of selection test. First round is Design aptitude test, that first round will be the written exam, and if you are shortlisted for the first round, then they will call you for the second & third rounds, which will be Studio test & Portfolio evolution. If you can be qualified successfully by these exams, then you are more than eligible to take admission for your design courses. Best of luck for your future dear.

There are however a great deal of things you can do to improve your chances of being one of the lucky ones. You can follow the below mentioned tips to increase your chances of making a successful career in Formula 1:
1) Research exactly what it is that you want to do
You need to consider your strengths and experience, work out exactly what you want to do and then focus on developing the knowledge and skills that you need to fit that job role. Understanding the different roles within a team will help you narrow your focus into a specific area, keep you motivated towards that goal and hugely increase your chances of landing your dream job.
2) Learn about and immerse yourself in motor racing:
Formula 1 is an entertainment business and the side of F1 that you watch on television is very different to the business that runs behind the scenes. To be successful in any business, you need first to understand it. If you arrive at interview with a good understanding of what the team needs and the pressures that it is under then you have a much better chance of offering yourself as a solution to that need.
3) Look beyond F1 at back door routes into motorsport:
It is not impossible for graduates and school leavers to get a job at an F1 team straight after their studies, but if this doesn't work out there are ways in via the back door.
