Please give me a short essay why I choose this as my profession
Yes. Other than engineering you have alot many options like designing, architecture, computers, BCA, genetics, robotics, gaming, agriculture science, biotechnology etc.
Firstly choose a course followed by the Institutes that offers the course. Then scan through the eligibility criteria, ie if there is an entrance exam or admission based on merit. If entrance exam then prepare accordingly.
If you have a particular course in mind, let me know, will help you accordingly.
Wish you good luck...
