Any free things to do outside of school

Hi, I am 13 and currently do not have a school for year 8.(i am going to a UTC in year 9 ) both my parents work full time - we are waiting for the appeal date but the school year is almost over -. I don't want to stress them a lot. So I am asking for suggestions on what to do with my free time. I do the 3 core subjects every day. However been stuck inside is not very ideal because of how much my screen time has increased, and my eye sight slowly decreasing. If you any fun places (like art, reading, coding,) let me know please. Thank you

i recommend any kind of cadets tbh, ik it sounds weird but its really fun. im in the acf, we do a lot of camping type stuff? shooting w rifles and shotguns, and i did parachuting just a couple weeks ago. it starts off pretty slow but ive met some great friends there, its really good for meeting people.
