Extracurricular Activities to increase chances of getting into Yale?

Thank you all for your responses! I am aware I need to raise my GPA, and I’m trying my hardest to get A’s. Wether it’ll be enough I still don’t know but at least I’m trying .o. I was told as long as I take all the classes that are thrown at me and do well, I should have a bigger chance than I do now. But I also heard EC’s are necessary so I wanted to try to fit that on my plate as well !
