FluffyBunny said: The others are correct that you'll do well to try and get practice with a few pentest learning boxes. Aside to that I would recommend getting acquainted with the basic grammar of at least the following: Python, Javascript, Bash, Ruby, Perl, Powershell. And when I say "basic" I do mean basic: know how each language structures things like loops (for, while, etc.) and tests (if/then/else, case/switch, etc.) and how they set and call variables.
