How to get started with contribution

[Prakhar Khandelwal via Gcc]

Hey !!
I, Prakhar Khandelwal, am currently in the 3rd year of my engineering and
majoring in Computer Science. I always wanted to work at a low level in
software. That's why  I want to contribute to your organization but
wondering from where should I start, as I am new to this world of
open-source. So, if you can guide me,  then it would be great.
Waiting for your precious response.!!
Regards.
