What now

Ok so I just finished high school and have decent knowledge of python. So I have around 5-6 months till college starts. Now what roadmap should I follow to gain a edge over my classmates and what all should I do to start my journey into being a professional software engineer. ( I have a natural interest in cybersecurity and full stack development). Any and all tips are appreciated. (Also please don't tell me to just quit CS just tell me what to do next)
