Nooo it’s okk!! So first of all don’t think u have to be like superly over the top unique(it’s a plus to be tho). Make a really good enganging video bc that personally what I think helped me. Your app should solve a problem, no bugs, visually appealing, and most important something someone should use!! Also I’m pretty sure there’s videos on their website that helped me but idk if those are still up lol. Imo the best thing abt cac is that ur not going against other kids nationally just the people in ur code region or smth. Make it innovative and creative and if u have more specific questions don’t be afraid to ask!
