B.Tech

You've seen some planes flying, perhaps solved some physics problem, and now by some misplaced "knowledge", planes have become your passion. This is worse than a teenage (these days it's earlier, isn't it? ). Crush - worse than an infatuation. Aero has no future, no good career path. Go for mechanical engineering if you care that much. I know you don't feel like reading my answer - your hands are itching to go for that downvote button, perhaps even to the report option - sure, go ahead by all means, but don't pretend with yourself that you didn't read this. I am trying to save you from a regret you will face after four years. Now, to answer your question, join a college that offers aeronautical engineering. Some have their entrance exams, for some, it is just through class 12 marks. Far too many options exist. Refine your question to get those details, or comment - I'll answer more specific ones.
