Top priority is to improve your communication skills and English a bit more.
This is just the beginning of your career. So develop your skills on what your Boss . Company expects you to do.
Initial days in industry will be felt vague, like nobody takes care of you and every one seems to be busy. Keep observing , learn your job, slowly start taking responsibilities.
As a beginner you may be born for mistakes, so start working and learn what to do and what not to do.
Life is a long journey, learning never ends.
Keep going, it is simple
