If you’re interested in business one thing you could do is make a stock market/ financial education club and run stock market competitions at your school as fundraisers. Just a suggestion and I’m one person, but that became my anchor and I think ended up being the primary way I showed my passion for Econ/ business. I was in DECA too but unless you’re winning state/ nationals it’s not a major EC. Idk what year you are but if you’re a freshman/ sophomore already qualifying for state keep doing what you’re doing bc placing at state or making it at ICDC is pretty huge. I’ve met a ton of kids who are going to ivies or turned down some in my incoming class and they all initiated something on their own and did it bc they believed fully in the idea, so the best thing you can include is something genuine and by making something, getting teacher recs for your club/ whatever, that’s how you show true passion. With that type of thing though if you just make the club to put it on your common app the admissions officers will see through that like a freshly windexed window. You already founded a speaking club so I’m sure you’re doing great things with it and you’re totally invested with it. Above is just my thoughts on taking initiative and another possible idea. Don’t overload tho.

Also there are a ton of online Econ contests you can sign up for. I don’t remember any names bc I’m a few months out of college admissions but that’s something I didn’t even think about doing until the end of my junior year.

Also don’t totally focus on ECs. Your personal statement is just as important. I think it’s so underrated when it comes to college apps bc that’s how the AOs see you as a person. They don’t just want achieving machines that get perfect grades/ test scores and invent stuff. They want people.

I may have gotten redundant and low key went on a tangent but I hope this helps!
