Hlo,

Atul 

Hacking are for those peoples who are interested in programming and those who are creative.

It doesn't matter what is your age and qualification you just need to be  friendly with your computer.

Your priority should be to learn various programming languages like-C,C++,python,java etc.For becoming 

a certified ethical hacker you can pursue  cyber security course in it and can also join

various institute like IANT.

Thanks.

Good Luck.
