Hello there guys I am an highschooler in grade 11 I am studying in cambridge international I want to pick Cybersec for my uni any advice?
 
I'd recommend starting with learning the basics of Linux. Over the wire Bandit is a good place to start. Also it would be great if you could expand on what you know, so that we can curate our recommendations.
 
im building a homelab anything i can do with that?
Not sure what level are you on currently.
Start small and then work it out with the flow of ideas.
Understand how software and systems work. You can start with installing linux on a vm / pc and writing small programs.
Depending on your drive, curiosity and hard work you want to put in , you will see the progress.
