ALSO YALL ONE MORE THING START SOME SCIENCE SIDE PROJECTS!!!!
If you get an interview, theyll ask you to make a resume type thing showing all the extracurriculars you do, but they make a big emphasis on including some type of scientific pursuit outside of the school curriculum, and its also super duper good if you can talk about it during the interview to impress the teachers. Right now part of one of my biggest hobbies is anodising different metals and trying to get different finishes on metals and stuff via electrolysis and I regret not starting it earlier so I could put it on my interview lmao. Also try find institutions that will allow you to be part of a research project or something
TL;DR do a buncha science based extracurriclars, or spam cool science experiements and film them for proof
