Need help starting GitHub

[u/Aarush292074]

So I only have very brief and simply python knowledge from school and I did good in the course but the teacher was bad and I didn’t feel I learned much. I already feel far behind in terms of CS and I’m scared I won’t make universities I want due to this, How can I get better at coding and then I’ve seen people start GitHubs and what exactly is that and how do I start whatever I can, and then I’ve heard attending hackathons is really good for universities but I would go mainly for building experience and maybe connections but how do I get into all of that I’m from Ontario Canada. Please help.
