Hi Bittu,
Ethical hacking career is not like that if you hold a certificate then you'll be getting loads of opportunities to flourish further. It requires lots of practice and patience to make your name rise amongst the top hackers. 17 is not the age to worry but to look for the aspects to grow and if you are interested in ethical hacking then first thing is you have to keep your nerves calm and score enough to get yourself enrolled in some college. Since you haven't mentioned your expertise level in computers that is why I am suggesting you to get into BCA,B.Sc or B.Tech in computers. Side by side you can enroll yourself in good training institute or search for online websites that offer Ethical Hacking course. There you will get more insights and build a community of like minded people. This will help you build your career in hacking.
